No spec, merely (nearly) every real world implementation.

Lots. Basically most browsers and servers, if "broken" equals "imposes a
limit on URI length". Each is different, but many break at something
like 1-2k.

Various security efforts (SAML, Shibboleth, others) are hitting this
problem when communicating credentials (ideally in signed XML) between
servers across a redirect. The solutions so far amount to hacks and
switching to POST.
