I see. Been using `avpops` for preferences and alike till now. Surely can be done with sqlops. But it's all DB-driven.
Lately, I thought I could unify everything around usrloc, including attributes. In the end - isn't location attributes designed specifically for this purpose? If there was a rpc to add/delete location attributes - I'd gladly use it instead of relying on DB, but it seems like there is no such?
