Ok, let's be clear: the "hockey" you're talking about is a derivative
of ice hockey, closely related to street hockey?

Although the wiki page sadly doesn't spell it out, I'd assume hockey
is "field hockey", given OSM's british origins. The sport you're
describing is neither ice hockey nor field hockey, so use a different
tag altogether.

Inferring is bad. People will always want to do queries like "return
the number of hockey-related objects" without having to apply a
million conditions like "don't count it as hockey if the surface is
concrete".

Don't worry about what "people assume". Reusability by machines is the
game here.

If the current tag is leisure=ice_rink, there's no need to suddenly change that.

I'd suggest:

leisure=pitch; sport=roller_hockey; and for clarity or extra marks,
add surface=*

(with apologies to Richard Weait).
