Do not worry. You have done more than enough. I have notice this delay
from a long time. But nobody else reported it, which is weird. I am
going to wait until emacs-29, for those changes.

Is there any workaround or recomendacion for the emacs-28 users with the
built-in org mode?.

Or that should be mentioned on PROBLEMS?

Best Regards
