What will happen after google kills APK sideload?

if im not wrong, in september google (the owner of android OS), with a new update will kill APK sideload, so that mean we cant play anymore with modded version of games, apps and so on...

i recommend to take a valid E-waste android (old i mean) that cant upgrade to the newest Android os to play APKs

I believe we'll have to use .zip archives then
