Comment:
I'm with Alex for most of the same reasons. Retrofitting the database
level behaviour of a parent class feels a bit fragile. Model inheritance
differs from Python class inheritance in a few ways and overriding is one
of them. A field validator is probably one solution here.
The reuse argument doesn't convince me a lot, either. If the field is
genuinely intended to be reused as unique, it should be marked as such.
It's not really subclassing when it's both unique and non-unique in
different situations -- it's attempting to reuse something of the same
name in different context, not using "is-a" relationships.
