is subrp/subr-primitive-p ever non-nil?

[Philip Kaludercic]

Evaluating this code doesn't generate any messages at all

--8<---------------cut here---------------start------------->8---
(mapatoms
 (lambda (sym)
   (when (subrp sym)
     (message "(subrp %s) => t" sym t))
   (when (subr-primitive-p sym)
     (message "(subr-primitive-p %s) => t" sym))))
--8<---------------cut here---------------end--------------->8---

For reference, M-x emacs-version gives me

GNU Emacs 29.0.50 (build 7, x86_64-pc-linux-gnu, GTK+ Version 3.24.34, cairo 
version 1.17.6) of 2022-07-13

and native compilation is enabled.

I am wondering if this is intentional or if it could be a bug?
