Double engine failure to EOL is routinely practised in FFS for most heavy helicopter types in CAT operations in UK and in so far as I know, worldwide.
The risk of damaging the helicopter in doing this exercise in the real helicopter are just to great when considered against the chances of it ever happening for real.
As a result of reent fatal accidents the methodology and emphasis on NR monitoring after the first engine has failed has improved along with the CRM aspects of running a relight drill.
TC is probably technically correct, that no one is doing real EOLs in MEHs. However the value of completing this exercise in a good FFS cannot be understated and is the best compromise to preparing crews well and protecting live airframes.
