Should Linux VDSO be using symbol version based on the released kernel?

The Linux VDSO uses a singular version string, different by
architecture, for all VDSO symbols e.g. LINUX_2.6.29 for s390x.
Should the Linux kernel be using LINUX_4.5 as the version string
for new VDSO symbols added in LINUX_4.5?
That way we can talk sensibly about what VDSO symbols were added
upstream, and talk sensible about the ABI/API being exported by
any given kernel via the VDSO?
Right now the version is really only meaningless version for
future compat support.
