I am close to publishing a package called user-keys.  The goal was to
assist in diagnosing and planning out bindings schemes.  So far it has
three main functions:

   - Show all shadows for a sequence
   - Show all sequences from a preferred list of sets
   - Show all sequences matching predicates

One possible next goal is to show emulation map updates and listing active
maps with symbols rather than raw keymap data structures.

I am planning to extend the predicate matching to work on mass-unbinding.
Right now it's useful for diagnosing all "stupid" bindings, which I
preconfigured to predicates such as, "modified shift keys" or "multiple
modifiers".

Part of the goal was to develop a transient interface to articulate these
views of the keymaps.  I'm not sure how that's progressing since there's
not quite enough functionality to leverage state and input re-use that
characterizes a good context specific interface.

I felt like it's a good time to show what's built and see if anyone has
ideas based on experience about difficulty getting a good high-level view
of active maps and what information they miss as a developer or user.

I attached screenshots to this issue since I haven't made a video demo yet:

Thanks

You are assuming that everybody is using QWERTY and US keyboard layout,
aren't you?

I finished a rough proof-of-concept for abstract commands on top of command
remapping.  I used a macro to generate a mass rebind expression.  I can
still use C-n and C-p.  I can rebind the abstract commands and all of the
other commands follow.  If I add bindings to #'abstract-next to C-; for
example, all of the re-mapped commands are available on that sequence and
shadow appropriately.

Pretty print the macro at the bottom of the user-keys-abstract package see
a mass rebranding expression:
https://github.com/positron-solutions/user-keys/blob/master/lisp/user-keys-abstract.el

The tests also demonstrate the outputs, but are less realistic.

I am currently using Emacs with all of the mentioned keys rebound by the
macro call.  The first example of growing pains I found is that Ivy
actually already uses a remap to next-line.  Since it wasn't a built-in
Emacs map, I didn't include it in my example macro.  I would have to work
on the macro and expression generation to handle remap detection when
performing a move, but this is more a matter of plumbing than complexity.

I was able to use my reporting functionality from the user-keys package to
identify maps to start working on.  The commented expressions in the macro
caused errors (binding in the widget-global-map affects the global-map?) or
strange behavior I don't want to invest time in before validating the use
cases.

What I would recommend for Emacs is to implement a first-class named-key
that doesn't have the implementation limitations of the remap only going
through one layer.  I would be able to focus on making user-keys into a
better diagnosis and generation tool if I avoid going too deep on top of
the remap-based implementation, which has the one-indirection depth
limitation.

I'll publish the package pretty soon with some small coherence
improvements.  While looking at emulation maps, I realized some of them
won't have symbols for example, so I need to figure out a way to represent
the idea to the user.  I've worked a bit on generating mass unbinds by
refactoring the reporting logic and it generally looks like there won't be
difficulty.
