Because they are not given there.  The main reason is: this is Lisp,
a function can have one name, a few names (neither of which is "main" or
"canonical"), or no name.

This is exactly what I have done.  See here:
https://lists.gnu.org/archive/html/help-gnu-emacs/2016-02/msg00219.html
for my approach (including a stupid mistake of using `make-symbol'
instead if `intern', promptly corrected by Michael H.)
