For a long time I had the idea of making up a tube with 36 valves for
use on one of these rims. That way you'd eliminate the problem of
having to actually look for the valve, and maybe even rotate your wheel
before you could pump up your tire. I was hoping to use 18 schraders
alternting with 18 prestas so any pump would work too...

You could use 12 each of Schrader, Presta, and Woods valves. Or 9
each of the same plus 9 quick-connect air hose chucks.

QC chucks. Best idea. Ever. Why not?

And now for some complete sentences...

Why don't we have a nice valve that offers secure closure, secure
attachment, and quick release without pressure loss? Something like
an air hose QC (but rather smaller and lighter) would be great!

What's wrong with presta?

Attaching and releasing a nozzle to inflate it or a gauge to check
it always involves some air escaping (at least, for me). Also, in my
experience, they have been fragile. I should have put "robust" on
that wish list too.

Schraders don't spill like that, and are robust, but they're
relatively bulky for skinny-tire bike application. Some common tools
for schraders require you to contact at a perfectly-held angle for
their seals to engage the end of the valve (others seal around the
side of the valve too, much better).

Finally, neither has the nice QC-ness that I like in pneumatic tool
couplings, which is the main point I was considering in the quote
above.
