When using //cut or //copy, entities are always copy with or without -e flags, in code it's unused, so I either the code or the documentation is not right :)

yea it got lost when entity support was rewritten and no one got around to re-adding it i guess. thought there was an issue for this already but i guess not.
all that needs to be done though is that ForwardExtentCopy needs to take it in as a parameter and not create an ExtentEntityCopy if it's false.
