Flying through known or forecast icing

A bit of a distortion.
The phrase in the regulations is "known icing conditions". A forecast
that
mentions icing satisfies this as the conditions (leading to potential)
icing
are indeed known -- if you have read the forecast -- and you are required
by
regulations to obtain all relevant information for the flight which
includes
a weather forecast.

Many pilots try to parse the requirement as "known-icing conditions"
whereas
the FAA has defined it to mean "known icing-conditions" -- a subtle but
inportant difference when it comes to defending oneself against a
certificate action. A forecast of icing constitutes "known
icing-conditions."

What you say appears to have been true in the past, but not currently. As
noted earlier in this thread, the FAA now defines the terms as follows:

"Forecast Icing Conditions--Environmental conditions expected by a National
Weather Service or an FAA-approved weather provider to be conducive to the
formation of in-flight icing on aircraft."

"Known Icing Conditions--Atmospheric conditions in which the formation of
ice is observed or detected in flight."
