Comment:

 It's by design that migrations are generated even if no database changes
 are required (see #22837 for the rationale). We should probably document
 this if it's not already as this is becoming a FAQ.

 We should also look into if we can avoid the `DROP DEFAULT` SQL when it's
 not required.
