Could someone please explain to me how that is easier to keep track of?
I've seen a repository like that .... it was a total, horrible mess of
cross--level dependencies and spaghetti externals that no amount of
documentation was able to untangle. The projects that lived in it died a
horrible death.

Ok, so symmetry aside ... If you look at almost any reasonable text on
configuration management, it talks about trees and similar hierarchies
of branches. But because, unlike some other version control systems,
Subversion does not easily lend itself to structuring the /naming/ of
branches hierarchically (except through tricks like dashes or dots in
the branch name), I'm not proposing that; I'm proposing the exact
opposite, that we /simplify/ our branching schema, not complicate it, by
putting all branches in the same bag. We only keep the tags and branches
namespaces separate because that's a useful separation.

(I'm somewhat surprised by CMike's apparent accusation that I'm
proposing something /more/ complicated than what we have, maybe I
misread it.)

Anyway, I've seen any number of times, in real life (and had to deal
with it, sigh), that making trunk special in terms of naming causes
problems. Unfortunately I can't bring those examples and show them here;
inhuman restrictions, don't y'know. But I could dig in archives, too, I
seem to recall some examples of that from a few years ago.

(And by the way, conceding for the sake of argument that /trunk is
special, I can't see why it would be less special just because it was
called /branches/trunk)
