I agree, this does not seem like a good design. In my case at least, these are pretty slow database queries as well.

I assume it's related to #104, but there must be a better way to handle that? For example making a note in the documentation that when adding the package to an existing project, use files as the source until migrations are completed? I had the same issue when I started using the package, but just performed the migrations manually, also no big problem.
