Are there any objections for removing SHA-224?

I note, for example, that Microsoft has chosen not to implement SHA-224. It
provides less security as SHA-256, but at the same performance cost.

I'm trying to think of a compelling reason for implementors to implement
SHA-224, and I can't find one, other than for completion sake. Do we have
any use cases for it?
