New Feature: Space Specific Display Names

Perhaps more useful than streamlining full on account switching feature would be to have multiple personalities or Display Names available under a single @username:domain account specific to each Space

For example in the Main area on matrix.org my Display Name is "instantchow" however, in my Private/Public Space "Red Neck Yacht Club" I want my Display Name as "Yachti Yachtmen" (because that's how they know me over there!).

Spaces should have a way to customize the user's own Display name here because, just like in real life, groups/clubs know know people as different names/handles.

Some groups know me as Bob

Some Not

Not for infosec, for UX

So the idea is not about multiple account being mathematically impossible to be associated (but that's fine too), but more of a nice user experience that enables users easy context switching between multiple clubs/groups/friends without the hassle of choosing one handle v first name v full name that works universally (a difficult or impossible task)

Again, it's not a security concern, if a user wants to hard split their accounts, by all means, air gap to systems, make seperate accounts. This is not for that user. This is for the casual user who needs the chat platform to be a better analogy to IRL social groups.
