The :args syntax has the problem that it can only be explained/defined
by explaining how args work for functions and how `interactive' works,
so from a conceptual point of view (say, explaining to someone who doesn't
know Elisp yet) it's not really simpler than the full (lambda
...) form. IOW the only gain is a few characters.

Indeed, that's incompatible with lexical-binding.
As you know, I find this to be a *major* downer. But the only
alternative would be to define a new macro (like you've done), which
implies a larger change, and added complexity: since we're not
going to deprecate define-key, it means we'd simply have yet another
slightly different way to define key bindings. I already dislike
global-set-key and local-set-key, FWIW.
I think if we want to make it easier for users to customize
key-bindings, we should take a step back and look at the
larger picture, trying to see exactly what it is that's hard.
Maybe then we'll get a need for something that's substantially different
from define-key (and in which your ideas can then easily be integrated).
I'm thinking of things like tweaking key-bindings via Customize, and/or
being able to specify keybindings for specific major modes (without
needing to go through add-hook or eval-after-load), ...
