Feature request: a way to manage your email address' association with mxids independently of a homeserver

[lampholder]

Problems that can exist today:

• email address is associated with multiple mxids (on multiple homeservers)
  • if the most recent? association is with an HS that doesn't support invites, invites to your email address will fail
  • email invites likely go to the wrong mxid whatever happens
• email address is associated with a mxid on a dead HS
  • we try and fail to send the matrix invite without falling back to an email invite

I'm not really sure what this issue is asking for.

• email address is associated with multiple mxids (on multiple homeservers)

An email address can only be bound to one mxid at a time.

• email address is associated with a mxid on a dead HS

That sounds regrettable, but orthogonal to this issue?

If these are still problems, it would be good to open new issues with clearer requests.

email address is associated with a mxid on a dead HS

This would be covered by #485.
