    I read the ice here was sub-surface so no significant coma would form.

    Luckily their timeframes are in the billions of years. In 560,000,000 AD they will come and smash us.

    'Oumuamua got closer to the Sun that Mercury does. Even if the ice was covered by a surface layer, I'd have thought getting that close would still produce enough heat to melt it.

    A newly published photometric study (doi:10.1038/s41550-018-0398-z) indicates that Oumuamua is tumbling chaotically which would suggest that it has suffered an impact (quite possibly around the time it left its parent system). This tumbling motion will take something on the scale of a billion years to damp out (spin stress/strain tidal braking).
