It’s insane to think that an extension with the ability to snoop on all your requests is more privacy oriented than one that can’t.
It’s insane to want extensions to snoop on all your requests in an attempt at more privacy.
Well, I would allow it for one specific extension that I feel does more good than harm for the capability. Call me insane.
It only sounds insane because you're saying "want extensions to snoop" to describe "want extensions to run a function call locally".
It is a permission that could be used by a malicious extension to snoop, but that is far from the only use. Wanting the permission != wanting snooping.
