I do understand, I believe.  I'm sorry if I gave you a different impression.

Here I, respectfully, disagree.  I understand that this has an unwelcome
effect for your particular setup, but I think that that's because this
setup made a brittle assumption about an undocumented and incidental
property of `text-mode` (the property of not providing any capfs).

Indeed, it's easy enough to adapt if you happen not to like this capf.
Which is why I don't think a dedicated user option is in order.
Regarding this specific way of adapting, my suggestion was instead to go
with something that still allows you to use word completion in text
buffers, but that's just a friendly suggestion, and maybe you simply
don't need word completion at all.

I appreciate your advice and your valuable user perspective.  As I
mentioned earlier, I think that such a user option would be redundant.
I wonder how others feel about this, though.
