but how does it do this - this is my point, as soon as you want to put
a value in the datetime control (and everyone does this when
re-displaying a form) you use the ability to put the hint in - despite
the fact the hint is more important now, as the user obviously didn't
understand it the first time!

This has already been discussed, and it's demonstrated that this is
not a satisfactory discrimination for testing support for datetime -
there's no point just saying it again, I'm certainly not going
suddenly to notice that FireFox (for example) all of sudden fails that
test.

It's a simple fact that the above is not a suitable discriminator for
WF2 support.  What is?
