how can debian ensure that? you are requiring that all user's read and
adhere to the debian bible. if they ever do anything else (such as
download gcc.tar.bz2 and build+install it from source), this isn't
true anymore.

btw: i consider my ability to do this a critical part of what makes
linux appealing to me.

"should": no doubt about that. "will" ???

when ardour runs as root, it can trivially be caused to do anything to
the machine, ranging from a DoS caused by using SCHED_FIFO and
mlockall(), to scripting by using the GTK+ engines system. the GTK+
folk are very insistent that no GTK+ application ever be run suid root
for this very reason. they think that you should build a "helper
application" to deal with this issue, which just doesn't cut it in a
system where the integration between the GUI and the core of the
program at run time has to be so tight.

if you write a program that uses a GUI and SCHED_FIFO and mlockall()
and you run it as root, all security bets are off.

when i installed debian for my brother a month or two ago, i never saw
anything about the BTS. i've never heard of it, and nothing during the
install told us about it. we had a fully functioning linux system with
ardour running, and any bugs that he discovered would have been sent
straight to ardour-dev.
