If RPG Maker MV/MZ players did care about having 500 copies of nwjs.dll (as well as completely useless locales and swiftshader caches that they can safely delete except for one locale), they might actually decide RMMV/RMMZ isn't worth the bloat. Especially when the game doesn't even need any Node.js library in the first place.
Of course, there are the older RPG Makers. But are they still trendy? Do people now know how to get rid of "RTP not found" without installing the RTP 100 times and just doing it right, you know, extract the RTP, point to the folder and register the pointer, or having the developers feed them the RTP over and over again without their end users realizing they'll end up with (dozens, hundreds of) thousands of duplicate files?
For RMMV/RMMZ: "You might not need jQuery" in another flavor. The end user may sometimes argue that they can easily mod the game using JSON and JavaScript, which is a very valid argument to defend the engine's usefulness but still won't help with the bloat.
If I recall correctly, F95 encompasses everything as "RM", which doesn't exactly help. I can name a few games made with RPG Maker 2000 that somehow manage to outperform MV/MZ games without even running into the expected encoding issues. But would they be popular? Not really. Everyone's all about having 4K resolution on their 320x240 phone nowadays.
That post was more of a rant than anything else. Must be getting tired, sorry.
