I was thinking the same... Without that, we will be discussing
performance issues without a reference point. But the problem is, I
am not bored. At all.

That's one possibility, but it has drawbacks: we must maintain two
versions of backup-files, we have to keep them fully compatible
(which may prevent us from doing clean-ups that would speed up the
shell counterpart), and we still have the bloated configure script.
And the test suite would only test one variant at a time.

So it doesn't sound terribly appealing to me. But I can be convinced,
especially if the Debian folks say it would make their life much
easier.
