This is because certain features (like haptic feedback and adaptive triggers) work by exposing them as an audio device to the host system, which isn’t functional over Bluetooth (the reason I heard is that Bluetooth just doesn’t have the latency for that, if there are third party projects that have found a way around that then great!).
All normal controller features work fine, you just can’t use some of the PS5 exclusive stuff. I don’t know of any games, including PS5 games ported to PC, that absolutely require the wired gestures.
Note this applies to all PCs, regardless of OS.

Was building a PC years ago, while in college, and forgot to get a Windows license (eventually got one through my university). After finishing the build I was so hyped to use it I just installed Linux (had played around in it in a VM in the past, so I knew my way around).
Got used to using Linux as my main OS after that, and stuck with it. Paying for a $100 OS is silly when the free alternative is just as good (though, I admit I do still use Windows for work).
Note: I used to game in Windows as well, I don’t do that anymore. Thanks, Steam!
