There has never been any ABI stability requirement for 'isapc'
as it is not a versioned machine type.

Migration is irrelevant unless someone steps forward to
commit to long term versioning of the machine type.
But migration is also how we implement savevm/loadvm,
which are useful even when the machine type is not versioned.
So please don't put in migration blockers or similar that would
break that.
