Well, you've made me question one of my assumptions, anyway. I've always
assumed that proprietary shops were much more likely to choose
ClearCase, Perforce, etc. I can't immediately think of a way to prove
this one way or the other.
Even if you are right, you might find it a bit difficult to sell changes
really weighted toward the other model, because anyone working on
Subversion (itself an open source project) would be naturally biased

It may be a nebuluous statement, but it's almost guaranteed to be true.
Greg Hudson said that from a perspective of a developer. From more of a
user perspective, it's not uncommon for me to experience working copy
weirdness. So I'm a bit frightened by the idea of making the existing
system more complex when it is already not working perfectly for me.
GCC and X11 are mature systems - they weren't originally designed with
all the complexity they had now. There was much more time for debugging
and refactoring between stages. Even so, if new alternatives appeared
that what I needed as well with less code, I'd probably switch.
And I think in those projects there is a lot of amount of resistance to
complexity without sufficient justification. You've made it pretty clear
to me anyway how important this change is to you, but it took the
details in this latest message to do it.

Okay. With these details, this is much more clear to me. I understand it
is a real problem for you. And the same for the inodes to some extent.
