First, I have to admit that the code of `gnus-mime-delete-part' is
more or less copied from `gnus-mime-save-part-and-strip' (see the
FIXME).  In `gnus-mime-save-part-and-strip' ShengHuo added this check
deliberately:

But maybe we can change the error into a query like "Deleting parts in
complicated MIME structures might not work.  Are you sure?"?

Bye, Reiner.
