This isn't so bad. Unlike other mobile OSes (namely iOS and HarmonyOS), you will still be able to install whatever you like on Android over a USB debugging connection (adb) without any developer verification.
It doesn't take much effort to enable Developer Options, plug into a laptop and run "adb install whatever.apk". It's kind of like the floppy disk era again, having to physically insert things into one's computer to install software. Not a big deal.
