Suggestion: help-enable-completion-autoload nil

I have not understood exactly what help-enable-completion-autoload does or why, but in short, I managed to speed up my C-h f and C-h v quite significantly on Emacs 31.0.50 by setting this to nil, taking them from ~2 seconds to ~0.2 seconds. Only affected Emacs 29 a little bit.

I suspected something was weird because I ran into the following error while I tried to complete to the symbol org-node--series, which rests in the file "org-node.el", and the backtrace shows that it tried to load files "wip.el" and "wip2.el" that I have in the same directory which contain no autoloads nor provides, and that's where the void-variable error comes from. The code in there does not work, but I did not intend the files to be loaded by anything.
