The main reason I see for authorizing other encodings is to be future proof.

When people designed old protocols they thought ASCII was here to stay.

So, I think we should learn from the past and not set in stone that all files must use utf-8, maybe something else will arise and be better for some unsuspected reason, and people will want to use that.
