Of course they shouldn't rename back, but the breakage in
this case will be seen only to the upstream authors and the
distributors who compile the package, but never to the end-user.
They'll just quickly release the update without troubling the user.
This way kernel could force the uapi changes without too
much troubles, and, for example, when it stopped to use
.fs/.fs fields for FS/GS, it could actually reasonably do that.
