Absolutely any feature present in a mainline product that isn't present in a prospective competitor will become a gigantic and unresolvable issue for any detractors. "gitlab can't X" "You can just do Y in gitlab to accomplish that, it's fine" "but it's not X, it can't do X" If a competing product is anything short of a reskin of whatever the current service, it is unacceptable and unworkable. Having personally watched this dynamic play out in my co-workers, I don't feel inclined to criticize gitlab for re-implementing lots of github features.
