bits/syscall.h is autogenerated from linux-libc-dev, so it indeeds
contains the latest definition from this fine. This is not something
new, this has always been like that.

I am not sure about that. This kind of new features are usually detected
by the configure scripts of the software, given anyway that the presence
of the syscall definition doesn't imply that the running kernel has
support for it. Also I am not sure Policy 3.5 applies there, most of the
packages work correctly there, so the dependency is not "required" for
packages to "work correctly".
