It doesn't bother me (a priori) if you add something, without
breaking anything.  Subtracting functionality is a different story.
Including `all-completions', `minibuffer-completion-table', etc.

I don't understand why you can't use lax completion in connection
with the existing framework (including `all-completions',
`minibuffer-completion-table', etc.).

I (and others) have been doing that for years, including for many
different kinds of lax completion.  What is so special about what
you think you need?

You no doubt have your reasons for doing things your own way.
Why not do that in your own library (compatible or incompatible)?
