You are right, currently stubdom doesn't work with passthrough.
I have a patch series to make it work but it is not finished yet and I
have been pulled on other projects; I hope to resume my work on that in
the near future.

In any case the fact the currently passthrough doesn't work with
stubdom is not a good reason for introducing even more problematic
changes.
