Yes indeed that is what the spec says, but pretty much all smart phone
platforms have ignored these and still managed to pass GCF.  I wonder
how they do that?

Same with this one.  On a modern platform you use the browser all the
time for stuff unrelated to the SIM.  Do you really expect that someone
will modify Mozilla / WebKit / whatever to send these reports?

Think about this one in the context of Meego.  This information is
simply not available.  We're running on a linux desktop, nobody really
knows whether one application is hiding another one or whether the user
is generating events or not.

Try coming up with these APIs first, if you find them turning into a
disaster area then it should give you a good indication of how likely
they are to be accepted.
