It's the only decent guide I know of for it at all. I assume it would be very similar. Sorry for not answering what you specifically asked for, I have no other information regarding it.

Protontricks should show all of the steam wine prefixes. I think the worst thing to get working is net framework, if you get that to install correctly never touch it again as you have been blessed. This is one of the better guides but I didn't personally follow it word for word. Needs a lot of tinkering. Frankly I got it work for a bit, but then net framework somehow uninstalled and it is such a hassle to get it to install back into the prefix I gave up and put it on a second drive on Windows. https://steamcommunity.com/sharedfiles/filedetails/?id=3440317058

It's not just GTA either, it started with unfinished texture packs for minecraft, and clothing addons for the sims. Now its every game seems to go crazy with this paid model. I mean the fact cars for LSPDFR will cost as much if not more than GTA itself, for high poly optimized vehicles with hardly realistic meta files is insane. Only way to make a change is to not buy them and stick to the thousands of free mods.

It's possible but not easy, RPH itself is quite a task to run on Linux.

Its part of the pain of modding a game that doesn't support it while having 3 different hooks fighting to load at the same time. (SHV, RPH, SHVDN, etc)

You can select different levels of usage, its not just a yes or no option. It's required for files going forward when it comes to LLM written code. Stuff like the tab complete and just research itself needs no disclosure.

I'll be blunt here, as someone who is checking these files I find that most AI coded plugins have severe flaws and even performance issues. A big part of it is due to how lacking docs for RPH are. A very common thing I see is a loop in the main method to "keep the plugin alive" Frankly its not a 1 way mirror when it comes to transparency, especially since you can leave a note about what it's used for. There has been a total flood of plugins written by LLMs that do not even do what they claim so we have had to start handling those situations, and the other side is a whole lot that just barely function. The goal is to keep users who do not know better informed and allow them to easily make the choice themselves. Another situation is devs who spend months creating something by hand just to have someone else try and clone it feature wise with a couple prompts. It can be quite disheartening for those who create the quality code LLMs use to learn without permission. Think of the system like credits, you didn't write the code, an LLM simply just uses other people's code it was trained on to do it.
