I wondered about that, too, but came to a different conclusion:
dpkg-buildpackage is a rather low-level build tool. It IMHO also needs
to work in some (non-Debian) cases where some interaction is needed
during the build.
reprotest, pbuilder and friends on the other hand are meant to be
fully-automatic tools geared towards no user interaction at all.
This also fits with Mattia's comment that pbuilder also unsets
$DISPLAY and it's on the same kind of level as reprotest.

JFTR: It doesn't fail. It's just stopped and waiting for user input.
And no, it doesn't make those popups on a normal build, probably
because $HOME exists.

I'm torn here. While I see your point, I think that's something that
should be done generally in the tool chain. It's though debatable
_where_ in the tool-chain it should be done.

Yes, that would help in this case, too.
