Why are /usr/lib/pam*.so in FreeBSD-runtime instead of FreeBSD-runtime-dev ?

For reference:

# pkg info -l FreeBSD-runtime | grep "pam.*\.so.*" 
	/usr/lib/libpam.so.6
	/usr/lib/pam_lastlog.so
	/usr/lib/pam_lastlog.so.6
	/usr/lib/pam_login_access.so
	/usr/lib/pam_login_access.so.6
	/usr/lib/pam_nologin.so
	/usr/lib/pam_nologin.so.6
	/usr/lib/pam_securetty.so
	/usr/lib/pam_securetty.so.6
	/usr/lib/pam_self.so
	/usr/lib/pam_self.so.6
	/usr/lib/pam_unix.so
	/usr/lib/pam_unix.so.6
# pkg info -l FreeBSD-runtime-dev | grep "pam.*\.so.*"
	/usr/lib/libpam.so

It might just be that part of the criteria is
the naming match lib*.so . But by type of content,
the status would be less clear. So:

runtime:

-r--r--r--  1 root wheel uarch 13696 Sep 24 08:03:12 2025 /usr/lib/pam_unix.so.6

runtime-dev:
lrwxr-xr-x  1 root wheel uarch 11 Sep 23 15:06:33 2025 /usr/lib/libpam.so -> libpam.so.6


Note: the test context is somewhat older:
