Well "refs get" is even harder to discover (it is not even in Git
2.50's manual that is available everywhere on the net), so difficult
to discover is not a good excuse.  In a sense show-ref was invented
exactly to serve as something like "refs get" you are writing, so I
wonder if a better approach is to extend it instead of introducing
a new subcommand in a distant place from it?

Perhaps "show-ref --verify --no-deref" or something that does not
dereference but works directly on a symbolic ref?
