But these new data transmission permissions seem to require us to declare many things anyway which are going to make users very confused.

I've seen this before, in principle.

Somewhere between an honest effort to not confuse non-technical users and a deliberate attempt to push out truly powerful addons (that might affect Big Tech sites' bottom line). I know fediversians are going to say "definitely the latter" but I can never quite make up my mind.

I guess there should be overrides a lá "I know this is potentially dangerous but I definitely know what I'm doing".

When will it become impossible to access about:config?
