I think this is once again a case of terrible implementation rather than them being against the idea.

I seem to recall them mentioning once that all account wide stuff had to be saved in a database and they didn't want too much stuff in there for stability reasons or something?

But if they changed it for stuff bought on mogstation, to allow any character on the account to buy from calamity salvager instead of the current mogmail system maybe they can get over that hurdle.

Of course can't really buy an 'emote' from the salvager so that's still an exception.
