There would be precisely that - a unidirectional migration (although I'd
say even a migrator is doubtful as part of an MVP - people can just set
up their email accounts again; it's easy with the DB).

One day, using an existing profile without data loss might be possible.
But to say you couldn't try Thunderbird++ until that was possible is
surely not true.

Sure. But not everyone will need to migrate.

I want to focus on the word "Minimum" in MVP. Minimum does not mean
"works for me", it means "works for some large enough set of people that
we actually have a userbase".
