Do you think that this PR covers this issue #64?

I think it partially answers it - it sounds like in #64 they are trying to do traditional "Design time" migrations where they can just run migrations against their database or container using the ef core tools regardless of whether the app is running. However, the database container either doesn't exist or isn't accessible from local ef core tooling, which is why the example runs them during startup. I think this new doc shows them an alternate way of doing this, which they might be interested in - I don't think .NET Aspire supports traditional design time migrations at this point.
