Agreed. Tastes evolve. People want SUV style vehicles and I think Ford did a decent job with the Mach-E. I would hazard a guess that most traditional Mustang buyers aren't the sort who would consider a car that doesn't go vroom and smell of gas, so you've created a weird conflict between your loyal existing fans and people who want a practical vehicle. It'll probably blow over.
In 10 years it might not even be profitable to build a gasoline car. How many times has the Viper being canned and reborn? The only way to continue the Mustang badge at all is electric.
How well accepted is the Urus now in Lambo circles?
