As others have laid out, it depends very much on the depth of the analysis your company performance department has done. For us, we get options out to where you’ve made MSA and can continue/divert/return but once on the EOP we need to stick with it, as it could be going in a completely different direction to the SID, and to get from one to the other might involve flying through rock (and a heavy application of the Uncertainty Principle).
A typical EOP might read something like:
Engine failure before XXXXX, follow SID to XXXXX then turn left to ABC to hold or return
Engine failure after XXXXX but before YYYYY turn left to ABC to hold or return
Engine failure after YYYYY continue with SID until above MSA then continue or return
