You can't actually assume that the grub binary on the running system is
the same version as the one currently booting the system. It probably
tends to be if the distribution takes care to auto upgrade it when a
new grub is installed, but it doesn't always happen.
Of course in the case of a distribution, it's package management would
already have that information.
I am not saying adding this is a bad idea, I just don't believe it does
anything useful. I just believe it is trying to solve a problem that
doesn't actually exist.
