I experimented a bit, the following could be a starting point for such a
function. It just collects all functions starting with xhg-dvc:
(let ((xhg-commands))
(mapatoms '(lambda (x) (when (and (functionp x)
(string= (substring (symbol-name x) 0 (min
(length (symbol-name x)) 7)) "xhg-dvc"))
(add-to-list 'xhg-commands x))))
xhg-commands)

We could define a list of available dvc functions and look into each
backend to see what is missing
> - commands of specified backend that do not map to dvc commands
No idea, how to do that. Each backend uses a namespace starting with a
prefix, e.g. xhg-
Some of these functions are candidates for commands that should be
listed. But there are also functions that are only helper functions.
Just do M-x tla- <TAB> to see what I mean.
