I don't know - it just seems unwise to artificially limit a powerful  
API that is already exposed elsewhere, just because we cannot think of  
a use case right now.

But I'm not too hung up on that one, a simple list of mime types is  
much better than no filtering, so go for it.

How about allowing glob patterns in addition to concrete types? Though  
that might require extending the DS.
