That probably isn't something good for everyone, it makes trying to guess ids on a busy system so much easier than 60ish bits of random data (just get an id, try to add or remove 1, and if someone else happened to generate another id the same millisecond you've just found it?)

Whether the id is secret or not is a debatable choice, but there's no reason to make it easily guessable; at least that increment should be random with a somewhat large stride...

But in general anyway in a distributed system network latency etc will mean things are just "mostly sorted" which is good enough, keeping the last few inserts in order is much easier than reshuffling the whole db/index all the time
