Wait a minute. If we're back to the argument that some third-party 
vendor or group which claims to support ISO 639-3 coding doesn't support 
private-use codes, that's neither our problem nor the RA's. Private-use 
codes are an integral part of both 639 and BCP 47. That's not a good 
argument against them.

A better argument against private-use codes, for something like this 
where we expect either a 639-3 code or a BCP 47 subtag to be assigned 
later, is that data would have to be changed and that is inconvenient 
and unreliable.
