I tend to think of Hydra as "bindings that stick around" (to take the
wording on the first line of hydra.el), rather than "ways to show
available bindings of the current submap".  So, yes, I think it does
something else (something more) than what I understand you want.

And, BTW, if I take a hydra like

    (defhydra hydra-zoom (global-map "<f6>")
      "zoom"
       ("g" text-scale-increase "in")
       ("l" text-scale-decrease "out"))

and I press `f6` I don't get any help in the echo area (nor in the "lv"
area).  I only get that help after pressing `f6 g` or `f6 l`, so I need
some other mechanism to find those "initial" key bindings.

So in this respect, I think it does something less than what
I understand you'd want.

I don't know enough about it to have a clear opinion on that.
