I just mentioned it because switching accounts for writing wouldn’t be much code. Switching it and have all of your timeline and views refreshed would be a lot more code. This problem was originally what set me off to make a local relay (nostrdb), since switching accounts would be really data intensive otherwise.
I mean if people are doing that anyway by logging out and in, i guess we can just do it and take the data hit until we have nostrdb queries fully integrated.
