I agree that that alone is not an issue. However, the reasons for rejection
need to be clearly understood. The registration of language subtags should
be a last recourse, reserved for cases where the proposed subtag is not a
"normal" language in the sense used in ISO, or where ISO is very clearly
wrong in not encoding it.

We don't live in an ivory tower. Whether implementations would break should
always be a factor to consider.
