Theoretically, yes, it matters. It's ugly for a supposedly data-neutral
storage system to contain a set of hard-coded rules about what types of
data it treats in what way.

Practically, I cannot quantify the cost and benefit. It's certain that
there would be a benefit to some people, because we have several times
had requests to add this or that MIME type to the list. Let's see how
much interface code would be required to do this.

What sort of MIME-type handling APIs?

Don't know.
