Hi Eshel

thanks for confirming my understanding. So now, my only "request" would be to add Elisp code

to make it easier to manage the c-a-p-f.

My main concern is that they are people out there to whom the additional information provided

by ispell-completion-at-point is a burden more than a help.

Attention/concentration deficit is something we should really take seriously. Not only in this case,

but overall. I have taught emacs to some people and, just as an example, company, which I use

in all my programming modes in conjunction with eglot (a neat package, right?) was felt as disturbing

by some people, because they felt over-stimulated by all the options it gave to them.

Therefore I'm "making noise" now. Sorry I could not be part of the discussion back in January, but priorities

in life didn't include Emacs back then.

I don't think you're missing anything here. ispell-completion-at-point
is just a function that can either be in completion-at-point-functions
or not. The option text-mode-ispell-word-completion controls whether
text-mode adds ispell-completion-at-point to c-a-p-f initially, but
users can also always rely on add/remove-hook to manage it directly.

Best,

Eshel
