We also have pre-flight checks for move operations like live and cold migrations, and I'd really like to keep all the conditionals in the conductor, because it knows better than the scheduler which operation is asked.
I'm not sure what "pre-flight checks" we have for cold migration. The conductor migrate task asks the scheduler for a host and then casts to the destination compute to start the migration.
The conductor live migration task does do some checking on the source and dest computes before proceeding, I agree with you there.

Agree that building more special rebuild logic into the scheduler isn't ideal and hopefully we could resolve this in conductor if possible, despite the fact that ImagePropertiesFilter is optional (although I'm pretty sure everyone enables it).
