They shouldn't: we have a lot of commands without dedicated bindings.

This command will retain some marginal utility, for some users out there 
(though I don't know who or why), so removing it doesn't make sense.

But its utility is incommeasurable with the binding it's taking up.

Let's announce in Emacs 28's NEWS that we intend to remove (or take 
away) the binding 'C-x v b'. Just like we did with the TAB binding in 
*xref* buffers.

"No one" is a very strong criterion.

What if 2 people total, out of all users, were using this command?

Would you still deprecate it, with intent to remove? Or would you still 
keep the binding?
