Not sure. Maybe it will make back-patching a bit easier, but we don't
normally consider back-patching cosmetic changes, which is what this
really is.
I don't buy the suggestion that third-party extensions would be able
to rely on it across versions. They can't know if they're going to be
compiled against the latest minor release or not. So it's just a
question of whether it'll improve matters enough for our own
back-patches.
