I'm with Ferenc on this; bonding isn't necessary to install the system, so
I'm loathe to put it into d-i.  In particular:

This makes it a UI nightmare if all those questions are asked[1]; even if
it's only preseedable, it's still a pain in the arse.

To address your later concerns, if your switch is dumb enough to send
packets down a link that's down, fix your switch.  If your NIC/driver tells
the switch that the link is up when it's administratively down, fix your
NIC/driver.  If netcfg is leaving interfaces administratively up when the
system isn't using them, report an appropriately detailed bug and I'll look
into it.

All that being said, if a patch were to turn up on this bug that handled all
the questions in a preseed-only fashion, integrated well with the rest of
the netcfg code (it might be better to wait 3 months on that one; I'm
currently refactoring all the internals to make extensions like this a lot
easier to integrate), I would give it a fair assessment with a view to
merging it.

[1] Yes, I'm well aware that most of them would be hidden behind a "do you
want to bond interfaces?", but even asking that question would be
problematic for the vast majority of users to answer; I'm not a personal fan
of lower priority to hide this sort of thing either, because then you
bombard the advanced user with piles of questions they just don't want to
see from other packages.
