Yes, I’m sure I don’t care about either of those scenarios, as I think they will be so rare in practice as to not matter. I think “good enough” is a quick simple code change to have the newly created anon user grab the current trust level of the user it is spawning from. Probably one line of code?
We could always improve the behavior later if people start complaining about it, but I doubt that will happen due to the rarity of this feature being used at all.
I like to scale the engineering effort to the rarity of the problem, personally, and I am a big fan of “good enough for now” solutions, provided they aren’t hacky, and I don’t think this would be.
