Yes, those limitations are only for stock based ROMs and prevent downgrading to previous firmwares. AOSP/LOS ROMs are completely unaffected by this though it's still best to be on the latest firmware so you have the most up-to-date modems/best connection possible.
Edit: Just to clarify, downgrading is still possible, but only within your respective anti-rollback version. We're in version 3 iirc so you can downgrade up to 20o without issue but below that (20i/all of 10) will cause a bootloop (possibly a brick?).
I don't really see an instance where we'd benefit from downgrading since we have unlocked bootloaders and easy access to root but the option's there I guess.
