No, that particular compat setting is deliberately locked out for modders/mappers (I believe that Graf has made it clear before that he will never expose this setting, as he doesn't want people relying on this bug). With that being said, it isn't hard to restore the bug through ZScript, I've done so here
(feel free to use/edit it, details in the code). That code is designed for mappers, but could be easily modified to work as a general toggle for a user (I can help if you are unfamiliar). Remember that you will need to set the "compat_corpsegibs" CVAR regardless (i.e. "Crushed monsters can be resurrected" in the options) for this to work.

Must have used a different source port, because GZDoom does not expose that setting to users, as mentioned above. The only maps on GZDoom that normally allow ghosts are hardcoded in gzdoom.pk3
(search for "vile_ghosts").
