Thanks for trying this. I can confirm by encoding to an opus file that
metadata are present in liquidsoap's encoded stream:
% opusinfo /tmp/opus.ogg
Processing file "/tmp/opus.ogg"...

New logical stream (#1, serial: 3334dae5): type opus
Encoded with ocaml-opus by the Savonet Team.
User comments section follows...
        album=After Laughter Comes Tears: Complete Stax & Volt Singles +
Rarities 1964-1965
        date=2012
        year=2012
        artist=Wendy Rene
        title=After Laughter (Comes Tears)
        comment=LITA 080
        tracknumber=4/22
(...)

I thus follows that icecast must be the culprit here. Icecast's
handling of ogg streams is relatively complex and I wouldn't be
surprised that it drops the metadata packet when relaying ogg/opus
data but perhaps a more recent version or development snapshot can fix
it..?
