Nuking the existing LICENSE file and replacing with the canonical one is a good move when it's your own developers' work. They could easily have picked "a" MIT license or screwed up the copyright string, and getting this normalized from the moment the repository is published is important.

But it's important that this -not- get applied to outside work from forks.

It should raise an exception that causes a person to have to deal with the matter. I should not be surprised if I were to find that this is actually in fact so and the extra step is responding to a prompt which people got used to not reading.
