As a user, I don't care why they're implementing it, only that it's available. I've been complaining about this exact problem for years, so I'm happy that it is finally getting resolved (if it is getting resolved — Google's statements about what Android 12 will allow have been pretty vague).

Also, as far as I know, Google hasn't used the security excuse for not implementing it. I just assumed that this wasn't going to get prioritized over OS features that enable Google to make more money.
