The point is not whether I personally—or anyone else—is "looking at" the standard. The point is how many users are affected by changes. And that is a huge number: every user of a smartphone; every user of a web browsers; every user of a search engine, etc.​

Any proposed "unification" of the standards or of the registration needs to weigh the potential costs and benefits. For example, a merger of the standards would only be acceptable if it was purely editorial; but in that case, it is hardly worth the effort. A merger of the Registration Authority is likewise only warned if it does not disrupt the stability and established practice for adding codes; otherwise it would be a disaster.
