Yes, that would need to be deleted. However, we should then stick with
only the facilities that are used on all platforms.
ntp (12),-- NTP subsystem messages
logAudit (13),-- log audit messages
logAlert (14),-- log alert messages
cron2 (15),-- clock daemon messages
Are note universal. See this excerpt from the current glibc syslog.h:

When we claim to create normative names for facilities, we should not
cause backward compatibility problems for those facilities that are not
even mentioned in the relevant system header files. Claiming them would
essentially eat up the remaining four extension possibilities. For
example, I'd much more prefer to have a LOG_HTTP in the future than to
have a LOG_CRON2...
