Then we wind up with both the original tag and its temporary replacement
marked deprecated.  That's undesirable.

Unfortunately, the BU->MM change was grandfathered in, so MM is the
canonical value at present.  So if MM were to be deprecated by ISO in
favor of BU, we wind up with Deprecated fields for both tags, making it
decidedly unclear which the canonical form is.
