Many people use 'URL' to mean 'URI using the http: scheme', yes.

Absolutely.  OASIS have backed off using URNs as namespace names, and
W3C TAG strongly recommends using http: URIs for this purpose.

Why doesn't the same apply for e.g. http://[your committee]/namespaces/xxx?

Which has the additional benefit that as I mentioned before, you can
document your namespace at that URI...
