The time penalty is trivial, but it is literally all that these systems are doing besides potentially playing video game noises at you to distract you from reality even more — the entire non-auditory function of the system is to introduce a delay to invoke nostalgia in the user.
An actual driver's car, which isn't necessarily the fastest possible car, is enjoyable to drive on its own merits without anything fake. The main reason why shifting is fun is that you are actually doing something that needs doing, and you can derive satisfaction from doing it well. The more mechanical the car is, the more enjoyable it is, because the more you are effectively controlling that machine's actions to execute your will.
The computer generated fake shifting of EVs is a way of turning driving into Dance Dance Revolution. It has as much relationship to actual shifting as executing quicktime events in A Way Out does to escaping from prison, but it does seem to amuse some people. As long as it produces sales, it's a success, but I do predict that the popularity will wane rapidly as people learn to enjoy the actual EV driving experience. Being able to hear the tires before they start squealing is great. Of course, for that you are ideally in something light and tight, not a gigantic modern behemoth. Electric Miata, anyone?
