While I agree with you I did just want to point out one thing.

This:

it’s mathematically impossible to fake.

Is not entirely true persay, every hashing function does have collisions that can occur. But the likely hood that someone baked an exploit in that kept the application functioning while adding their backdoor all the while somehow creating a hash collision with the original fingerprint is practically zero and honestly if someone did pull that off, fucking hats off because that has to be some sort of math and coding wizard beyond most. I should also point out that the file size would most likely/have to be different so there should be other methods of detecting the compromised build regardless.

Sorry I know that was very pedantic of me but I did want to call that out because its technically possible but the actual likely hood has to be so miniscule its almost irrelevant along with the fact that other tells would surely exist.
