Thinking about the potential requirement to migrate people through 1.4
before going to 1.5: I don't really like that idea, because we went through
quite a bit of trouble to make sure our database schema management doesn't
generate as many errors in 1.5 as it did in 1.3/1.4.
But then, if we were to require people to move through 1.4, they would
still be confronted with the old behaviour we expressly replaced to improve
user experience.
All in all, I now think we need to migrate 1.2 and 1.3 users to 1.5
directly. As for 1.4 migration, that's probably already in place with the
sql/changes/ directory. Correct?
