IMO the big problem with this is for old APKs that were created before this new developer registration requirement- you won’t be able to install them at all without rooting or using a different vanilla Android version.

It prohibits developers from creating apps and maintaining their anonymity but it also prevents scammers from anonymously streaming people’s money with fake apps.

Will be a big problem if their developer registration process is difficult or used as a restriction somehow to govern who can register.
