Okay, it sounds like we're homing in on the central question here:

   "What and who is dist.sh for?"

If the answer is "It's for us to produce our releases with", then the
export changes probably don't belong in it.

If the answer is "It's for anyone who wants to roll some sort of
Subversion release" (or something like that), then the export features
start to make sense, and possibly so do a lot of other things. In
fact, it becomes difficult to know what features we can leave *out*!
After all, we know what it means for us to roll our own releases --
that's a well-understood task. But we don't really know what other
groups might be up to in rolling specialized releases of their own.
How could we ever judge dist.sh's feature set or interface with any
confidence, if go down this road?

Therefore, I prefer the first answer. I think we should consider
dist.sh to be the tool we use to roll our own releases, nothing more.
When we originally wrote it, we never envisioned it taking on any more
burden than that. Why would we try to expand its mission now? I feel
like the compelling use cases and examples just aren't there. Sure, a
few people have done it from time to time, but people do lots of
things that the Subversion project doesn't provide direct support for.
In the long run, it'll be much easier to maintain dist.sh if it has a
narrow, clear mission.

That's my $0.02. Justin, if I'm missing any important parts of the
argument you're making, sorry & please correct.
