I don't think this makes any sense.

In practice you are saying that in order to avoid mistakes, the local
admin must provide the BDF of the device to be passed through in two
separate places.

But that doesn't actually help.  If this is all properly documented
and so forth (ie, if the admin has a smooth experience and doesn't
trip over having dailed to "seize" the device), they will just
cut-and-paste the same value into both places in the config.

They will also mutter under their breath to ask why this is
necessary...

Ian.
