Vertolot,
DOC 8168 Volume II (PANS OPS) is a 'procedure writer's manual'. Only those who wish to discuss, or propose amendment of, IFR arrival or departure procedures need to be familiar with the contents.
Whilst this discussion was interesting (to some of us), it cannot be expected that the average pilot would have a knowledge of the presence - let alone the contents - of PANS OPS.
The procedures that are discussed/followed during an OPC should be those which are enumerated in the Operations Manual (OM). That a SID is constructed/flown AEO is something that should be known to pilots but it should also be set out in the OM - as should alternative OEI contingency departure procedures (EOSIDS) if they are considered necessary. In the absence of EOSIDS, there should be a statement of policy within the OM; as mentioned earlier, this might just consist of a statement of actions to be taken following an engine-failure at or before the some clearly defined elements of the CAT A procedure - when IMC. (Remember that before entering IMC, the aircraft must be operating in PC1 - i.e. there must be a transition from PC2 to PC1 at or before 200ft; the conditions for PC2 at 200ft are identical to PC1 - hence from that point, Subpart H points to Subpart G and does not contain requirements.)
The one thing that is perhaps not clear is whether (your) SIDs contain the specified gradient. If not, it might be appropriate for you to recommend that the OM is amended to include this information. When doing that, it might also be advisable to ensure that the other basic elements of SIDs are contained within an informational narrative.
