Comment (by Stephen Finucane):
Thanks, Mariusz. However, there is no reference to this anywhere in the
documentation, so at a minimum it is very surprising behaviour that is
likely to catch users out. Until we fix this in a backwards-incompatible
manner, would you be open to a documentation patch that calls this out?
Alternatively (better), could we log a warning when auto-generating
migrations that remove child tables in a multi-table relationship to
indicate this potential issue and suggest users clean it up accordingly?
