Best I can find at the moment was discussion around CAP_COMPROMISE_KERNEL:

Basically, adding a new capability for an interface can create
userspace compatibility problems (though perhaps in this case, it's a
new interface, so a new capability would be okay, but it's such a
narrow use-case and CAP_SYS_NICE fits fine).
