the caching server setting is Primal's warrant canary.
if they add a "bypass caching server, connect directly to relays" setting i'll be much more convinced they are good actors. and if it ever disappears thereafter, i'll know they've been captured.
...if they refuse to add it to begin with, i'll have no way to know which one it is, and i'll have to assume the worst. this is a healthy sort of pressure in a decentralized ecosystem.
i was similarly obnoxious about nsec sign-in, and to their credit they did ultimately add Amber login and i give them credit for that. this issue can simply go the same way and everyone will be happy
