Perhaps some or all of this could be common with ts-xen-install?

If a host is passthrough capable does that imply that the current job is
going to use it? It seems the two hosts with a passthrough-* host flag
are gall-mite and itch-mite which are certainly used for other jobs.

I'm not sure how this can be dealt with, maybe Ian has an idea, or maybe
you can just defer until a FreeBSD w/ passthrough job is created, at
which point you would surely know what to write here.
