So nobody can get away with a lie.
And yet devices do exist which lie.  I'm not surprised that vendors
vehemently claim that they don't, or "nobody would get away with it".
But, of course, they do.  And there's no way for us to find out if
they're lying!
But we'll never be able to figure that out unless we try.

Once we've tried we will have proof either way.
Which is why I think we should have that implementation.
Only then we'll know if it's worth it, both from the hardware and the 
application side.

Without an implementation it'll just degrade to a shouting match.

Cheers,

Hannes
