Hm, so there's no provision for ATC to report to FSS when someone declares
an icing emergency?

That would seem to have been the case in this instance, at least.

But I recall that about 20 years ago, I encountered clear ice so bad
in a Cherokee that I was down to 80 kts with full power and could
barely maintain altitude; so I told ATC I had to land and diverted to
Williamsport, PA.

After I landed and had a cup of coffee, I went into the FSS to see if
the wx was improving, and along with reports of icing, I was told that
one pilot had been forced to divert (no airport mentioned). It took
me a few moments to realize they were talking about me!
