I disagree, and think that's a perfectly reasonable migration. Of
course you might want to know in advance that the target host doesn't
support this option, so you can decide what to do.
I'd go a bit further - it would be good to be able to change cache=?
and all other values which are invisible to the guest _without_ having
to do a migration too.

No, that's migrating to a host which doesn't support a particular
device. Same if, say, the guest is using e1000 and the target host
doesn't have e1000 support.
