One of the ISO 639 customers with an ISO 639 implementation is IETF (IETF Language Tags), and the working group working on revising that spec to incorporate 639-3 asked me if I could get this matter resolved within the JAC. They have referenced 639-2 in the past, and need to continue to do so because the 639-2 collections have been supported. (There is the option to change to 639-5 in the future, but that is outside the plan of current work.) The instability caused by "(Other)" for some 639-2 collections is of concern for them, so they'd like to see that change in 639-2 sooner than later. (If it were done now, that would allow them to cover the stability issues in this version.)
