Since this is already an open discussion I'll append here a few other QoL additions to the API that would be extremely useful:
// Makes ped provide ID to the player like on the stop menu (w/o dispatch information as warrants/license validity). void DisplayPedId(Ped ped); // Rename existing DisplayPedId to DisplayRecordsCheck to avoid confusion. void DisplayPedId(Ped ped, bool noDelay) = void DisplayRecordsCheck(Ped ped, bool noDelay); // Makes ped frisk ped. void StartPedFrisk(Ped cop, Ped suspect, bool force); // Gets called when a ped gets frisked. Event OnPedFrisked; // Gets called when a ped gets dismissed from a stop. Event OnPedReleasedFromStop; // More options for vehicle/ped spawning, w/o actually acting like backup units (Perfect for creating units already on scene for callouts) Vehicle GetEmergencyVehicle(Vector3 position, EBackupUnitType backupUnitType, string agencyScriptName); Vehicle GetEmergencyVehicleWithFlag(Vector3 position, EBackupUnitType backupUnitType, string agencyScriptName, string flag, bool hasFallback); // Implement search/contraband to Vehicle. // More complex, would require some sort of vehicle inventory system. void AddVehicleContraband(Vehicle vehicle, ContrabandType contrabandType, string name); void ClearVehicleContraband(Vehicle vehicle); List<VehicleContraband> GetVehicleContraband(Vehicle vehicle); bool IsVehicleCarryingContraband(Vehicle vehicle); void RemoveVehicleContraband(Vehicle vehicle, VehicleContraband contraband); // Makes ped search vehicle. void StartVehicleSearch(Ped cop, Vehicle vehicle, bool force); // Gets called when a vehicle gets searched. Event OnVehicleSearched; @LMS

This is basically what we do already, yeah.  Just one extension method with an automatic model hash check.  We actually have quite a few other things there related to those peds as well like a method to remove clothes (for the shower) and then quite a few that query the shop.ymt data to do things like check if a female ped is wearing heels or to correctly apply hair styles (including the special underlay textures that each style has) among other things.

Update
Almost 24 hours later, I've skiped a few things I needed to do today to work on DLS and it works way better than the one I started the day with. A lot of features that were lacking when I put the put out the post are now available and the Siren Controller finally works just like I envisioned it. There still a few features lacking for a big 1.0 version to be published but for now it's working just fine. I've been contacting some vehicle modelers and having them check out the script and some were very interested, hopefully by the public release I'll get a lot of configuration files. For now I'll share some things that might help you guys understand the mod better. For quicker updates feel free to join the discord and get some sneak peeks at how development is going.  
ETA Update
I expected that development for this mod would be very extensive, but it's not been quite as much (although this week was atypically calm for me). I'm not going to set any ETAs on stone but expect to hear more updates and who knows a public beta by weekend (hoping for it). I envision releasing the public beta as soon as I'm certain of the script's stability and performance, most likely with the current feature list. For now, my time will be focused on optimizing as best as I can the plugin (mind that I'm in no means a professional in coding, I'm just someone with a hobby) and creating configuration files myself for some of the most downloaded Non-ELS vehicles published in LCPDFR.com.

A huge thanks to @Zak. for helping me setup a Discord server to more easily communicate with vehicle modelers and other people.

Thanks everyone for your attention and hope to be back bringing good news soon enough.

Love that you used my model! I contacted you on discord to possibly try this beta out for myself.  (Tyler.#9999)
