Let's address multiple problems here.

It's only marginally less pronouncable than devfs, but we should
drop this part of the discussion, since it's only opinions and
can go on forever.
Here's what Tom Sailer (sailer@ife.ee.ethz.ch) wrote about usbdevfs:
<quote>
Eh? Have you understood what usbdevfs is for? It's completely orthogonal
to devfs. usbdevfs is for usermode drivers talking to their devices, not
for application programs. Also the reason for usbdevfs is that the
locking
issues against device removal are hard to get right, I doubt it will be
easy to incorporate into another fs without seriously disturbing that
other fs...

Richard's reply here was concerning a syntax error in drivers/usb/*
in 2.3.48. This was apparently the result of some changes to
a file_operations structure, but:
whoever made the changes didn't update drivers/usb/*, which is
OK, as long as:
there is some open discussion of them. Was there?
I go thru the ~300 lkml emails daily, but I don't read
every one of them. However, I don't recall seeing any news
about a global data structure change. It would be nice
(IMO more than nice for Linux to continue to be able to grow
in size) if such global changes were discussed or at least
if subsystem maintainers were notified of them in advance,
so that we wouldn't be hit up side the head by them.

So /proc should have been named something else, like /sys
or /sysinfo, eons ago, but it wasn't, so we have /proc.
That doesn't make it all wrong.
