If the worst came to the worst - I bet you could come close to knowing the
card types by aggregating the results of all of the glGet results...which
is why I think that providing a good VERSION/RENDERER return doesn't
significantly help the bad guys. But lack of knowledge about the exact
driver version number is a pain - and you're unlikely to be able to
extract that from the glGet results.
Still, making a "fingerprint" from those glGet results would be a useful
addition to webgl-bench if we end up without meaningful VERSION/RENDERER
