Pretty much.the answer is simple, its not profitable. thats all companies need. profit. nothing else matters.
I love the freedom of a modular set up, but most PC gamers simply want low end PC and thus you don't see much support for those types of builds. PC AAA exclusives are pretty much done. Anything made on PC now that is even AAA simply has plans for console versions like PS5 and Series X later on anyway when those install bases go up.
I've said it before and I'll say it again....the number of people that will own next gen systems will be more then the number of people that own high end PCs BEYOND the spec of Series X and PS5. Cause you can own a PC more powerful, doesn't mean that is 100% of the PC install base, yet 100% of the PS5 install base...clearly owns the exact same fucking specs, thus a developer can freely exploit those features on Series X and PS5, they can count on everyone having those features, they simply can do that on PC and I'd argue PC has gotten more casual over the generations and the few hardcore PC gamers still building rigs, seem to be doing so not to play some demanding game, but just to get 8K of crappy ports lol So you'll see that install base keep shrinking as even myself, I'm looking for a decent set up, not I'm no longer seeking some high end thing. If all the fucking games coming to PC, will just be ports of shit on PS5, I see no reason for me to even waste time chasing the best GPU on the market.
To play what exactly? Ports? Nah. I was looking to upgrade to a 3090 and it looks more and more likely that I'll probably get a 3060 or something and call it a day. I just don't see anything even coming out that would really need me to have some beast system like back in the day where you actually really needed a powerful system to run some PC exclusive stuff.
