To clarify, what I meant by sub-keys was creating a derivative of the primary key, basically the sub-key acts as a two factor authentication, or authorization protocol as a method to allow access without exposing the primary key.

I wasn't necessarily implying creating multiple accounts off of one key per se, to put it in Bitcoin terms I meant more like a Xpub that can generate new addresses for you, not a Bip-39 that let's your interact with other Bip-39 coins using the same seed (NSec).

I meant more like if there's a questionable instance you want to explore but not put your main Nsec in, & talking about a way to resolve the discrepancies between Primal, Damus, and Amethyst, etc., I use one Nsec for all them but half of my notifications don't relay to other instances.

But to elaborate on the idea, a Sub-Account Key vs a Authorization Sub-Key.

I'm not saying you should, or shouldn't build it, I was simply throwing an idea out there, & I apologize if it upset you.
