Comment (by carljm):
I'm not sure the fix for #8280 is actually appropriate here - I don't
believe that by default orphan `.pyc` files should be considered as
present migrations. I think the practical hassles that causes to daily
development with e.g. git branches outweigh the purity of using the proper
Python API for module discovery.
The distinction here is that usually the presence or absence of a module
that hasn't been explicitly requested doesn't fundamentally alter the
behavior of the system. With management commands, it does a bit (they'll
show up in help) but not in a way that's likely to break anything. Here,
having extra migrations around that shouldn't be around in this branch
seriously breaks things.
If we made migrations discover `.pyc` by default, we would basically have
to document that `PYTHONDONTWRITEBYTECODE=1` is required for effective
local development in Django.
I'm not opposed to an option to enable `.pyc` discovery, but I am opposed
to making it the default.
