I don't see why.  Stability says that once a language subtag,
always a language subtag: nothing is demoted to extlang subtag
status.  So languages that are encompassed in 639-2 today
have the same status (language subtag) as languages encompassed
in 639-3 later on.

The more serious case is when an encompassed language is no
longer encompassed or its macrolanguage is changed.
We'd be free to change the proposed Macrolanguage: field,
but the Prefix: field and Type: fields would have to remain.
