OK, I'm good with that, but are you sure that the correct pgrp is
ending up attached?  I was concerned about the subshell pipeline not
receiving tty signals before, but now I'm concerned about signals
not going to the previously-attached group from which the subshell
is taking control.

As long as we don't have two forks fighting over who is the foreground
job, we're OK.
