IDAs tend to get reused quickly, which can cause race conditions. Any
reason not to just use a 64-bit counter?
They tend to become hard to parse/compare for humans after a while.
And all this is basically only for humans, so race conditions don't
really matter. Also a changed mount with a reused ID is easily
identified by comparing the other fields.
Hmm, smart humans only compare last few digits if they don't care
about 100% reliability, and dumb software compares 64bits easily...

Indeed.
And this is most certainly NOT only for humans, and race conditions most
certainly matter.
