Bah. That's just stupid.

Sure, if you have to use "cmp" to compare your builds, you can't embed
random one-time keys. Tough.

That's a problem with your environment, and not a technical argument,
it's a political one.

I couldn't care less. "Doctor, doctor, it hurts when I use a stapler
on my forehead".

Debian has lots of "rules". That doesn't make it right.
