Right, sorry, what I meant was this particular behavior (switching to SSLv3
client hello when SSLv2 is disabled) appears to have been in upstream openssl
since about 2005.  What's changed recently is that instead of patching openssl
to disable SSLv2 (and thereby not triggering the client hello switch), Debian
has started to use the no-ssl Configure option, which is what probably started
allowing this test to unexpectedly succeed.

Interesting, thanks for the pointer.

I'll work up a patch.
