What if the sources are only available under a proprietary source code
management system which requires $$$ to obtain? i.e., like Perforce,
Bitkeeper, or <shudder> Clearcase? (Although I dont think Clearcase
has anonymous access, so maybe it would be prohibited on other
grounds.)

Well, technically they did provide a copy of the Corresponding Source.
They may just not have identified which revision out of the
potentially thousands of revisions in the repository _was_ the
Corresponding Source used to build said binary. (I guess the lawyerly
equivalent would be handing over seventeen truckloads of documents in
response to a discovery request, in paper form, with no index? :-)
It's good practice for binaries to identify the version id used to
build them, for example: v3.8-rc3-26-ge7b04ac. The question is
whether it's important enough to add this requirement to the copyleft
license, given the goal of keeping its word count under that of the
GPLv3....
