All of these (with possible exception of completion.el, which I'm not
familiar with) determine how completions are shown and/or how matching
is performed, but the total set of completions (completion table) is
determined by the command the user invokes.
So they don't include anything that looks like a replacement for
'describe-command'. But when there is a standard command with a good
completion table, they indeed can enhance the user experience.
There are packages which create new commands (and might even have
something similar to describe-command), but they are usually tied to a
particular completion framework.

"Significant discovery framework" is something very ill-defined. From
where I'm standing, function and variable discovery based on completion
is already in Emacs, and we sometimes provide minor fixes and
improvement for it (such as this command). Sometimes we do request major
changes that would help it as well...

...and see them thoroughly rejected. So I think this is relevant. But we
might be talking about different things.

But which otherwise duplicate existing commands? This is a valid
concern, but I don't think we'll get a lot of them.

Do you mean like extensions of the completion-at-point interface with
that aim? I'm curious about possibilities, but so far we haven't really
discussed them here.
