I suppose it's a matter of taste, but altering behavior based on the
presence or absence of a stylesheet with a particular media value is
just hacky.

I understand the problem, but believe it should have been addressed by
fixing MQ instead so that "screen" can match alongside other types.
MQ is just designed badly here - "screen" is *not* mutually exclusive
with "projection" or "tv" (and maybe even "handheld").

But anyway, this is off-topic.  If you'd like to continue along this
vein, could we branch to a new thread?
