To be clear:

Shared object rules are not pre-processors, they have a GID of 3. They
use the same SID range as regular rules (GID 1).

Pre-processors do not use the same SID range.

Yes, it is important to use the GID:SID tuple when talking about
events, it is also useful to include the rev of the rule, so
GID:SID:Rev is preferred.
