What's the latest on "forecast icing = known icing"

Just use the airmets. If there is an airmet for icing, you can't go. If
there is no airmet, you might be able to go if conditions allow it.

An airmet for icing consititutes forecast icing, not known icing, according
to the AIM definition I cited.

Of course, if there isn't a sound immediate escape option in the event that
the forecast is right, the flight would be unsafe (in a plane that's not
certified for known icing) and (incidentally) therefore illegal.

I agree the flight would be unsafe, and possibly illegal under the careless
and reckless clause. But I think the issue of whether it would be
otherwise illegal hinges not on whether the a/c is certified for known
icing, but rather whether there is a prohibition in the POH/AFM against
flight into known icing conditions.

My "mature" Mooney, and many other older small a/c, do not have such a
prohibition in their documents.

Yup.

Yup, an AFM prohibition (rather than icing certification) would be what's
relevant to legality apart from the safety issue. But the scenario under
discussion involves forecast icing rather than known icing, so (according to
the AIM definitions I cited earlier) the only legality problem would be from
unsafe flight.
