It's not a "half measure", it's providing a sane upgrade path.
If we had not had the deprecation notice in place for createlang, I do
not think Magnus' proposal to remove it would have been accepted so
easily --- or, probably, at all. There is no such notice in place
for createdb or createuser, so arguing by analogy to that proposal
falls flat.
