I use `all-completions' and nevertheless am able to do regexp matching,
substring matching, and several different kinds of fuzzy matching.

Maybe you meant `try-completion'?  And even that uses `completion-styles',
which is pretty flexible (not in the way that I wanted, but at least it
allows for different kinds of completion).

I don't know what your problem is with using the existing framework
to be able to do "lax completion".

[I've written here many times about what I've been doing, and how.
And the code is freely available, for anyone who is interested.
But the point is not what I have been doing (unless you are really
interested).]

The point is that you shouldn't need to sacrifice `all-completions'
or `minibuffer-completion-table' just to be able to get "lax
completion".  At least not any lax completion I've ever seen.

So don't use `completion-at-point-functions', if they don't give you
what you want.  I don't use them.  That shouldn't mean that you need
to screw `all-completions' or `minibuffer-completion-table'.

`completion-at-point-functions', too limited or not, is fairly recent.
`all-completions' and `minibuffer-completion-table' are decades old.
They are solid, basic tools.
