Of course. They should not be using that line in first place.
As has been said multiple times, the whole idea is to get rid of the
passwd/group files.

These scripts will need to be changed, if broken. No way around it.

That's only because you are turning your back to the change, not for any good
reason.

And raise even more confusion in years to come.
Better to switch over once and keep it as simple and straight as possible.
It's not like it's an unreasonable change. In fact, it's the change long
overdue.
