Would be hard to follow an SID with 8% or higher required initial gradient with an engine inoperative.
But then in days gone by we had a pretty conservative performance manual. Standard procedure was to follow the SID and the performance took that into account, only if not possible was there an EOSID on the WAT chart of the runway. Nowadays we would never follow the SID, if no obstacles present (well, obstacles we have to consider) we just fly straight out for the next 30NM by which time we should be above the required minimum altitude.
