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

I apologise in advance as this is a topic done to death in the past,
but I have heard various bits of info on this recently, some quoting
FAA or NTSB rulings etc, and others disputing that they are relevant
because there have been more recent events including a clarification
in the AIM.

I am in Europe but this is potentially relevant to me because I fly an
N-reg aircraft (not certified for any icing conditions).

What is the latest situation on this from the USA?

The current AIM (7-1-23) explicitly states that "forecast icing conditions"
are *not* "known icing conditions":

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

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