The main concern is for cases where different applications would be usefully selected based on MIME type.

Exactly. The only case I can think of right now is a hypothetical "my mail reader displays TIFF inline but doesn't support BigTIFF so I want to launch an external application for that". This doesn't seem like a very good example so... any better ideas?

This needs to be weighed against the downsides of using a different MIME type. IMO: slower adoption by applications and perhaps user confusion. I'm uncertain how much this matters given the target audience for BigTIFF.
