Sure, you're right that it does not remove *all* text properties per se. It
removes, let's say, "all that it can" which is more than "all that is intended".
In my last mail I was attempting to explain what you're seeing in the second
issue you described:
> It allows you to toggle font-lock-mode correctly, which M-x font-lock-mode

This is again correct behaviour. When you yank the defun from an
emacs-lisp-mode buffer into a text-mode buffer, you're inserting text with
(most of) its text properties, except for the property `(fontified . t)'
because within the context of *this* buffer, the text properties have not been
applied with font-lock-mode and so this would be false and prevent font-lock
from doing its work.
To see how this works, try the reverse: yank a defun from a text-mode-buffer
(i.e. no syntax highlighting) into an emacs-lisp-mode buffer with
font-lock-mode active. Since there is no `(fontified . t)' property you'll see
font-lock go to work and the yanked text will be fontified.
If you dislike this behaviour that's also fine, there's a user option for that:
yank-excluded-properties, which you can set to t and have what you expect as
correct behaviour (which fwiw is what I have it set to).
I hope this clears things up for you. Unless there's any outside objection I'm
going to fix up the command in master to reflect as pasted above.
