Dunno about that. The implementations I’ve seen so far default to /dev/random and make you jump through hoops to get the monotonic counter, so if you manage to enable it they should assume it’s what you want. I’ve actually used them effectively in a couple of NoSQL problems where I didn’t need cryptographic security, just distributed timestamps - I was creating two sequential events (create and update), and they had to always order one after another, even though I created them in the same loop and millisecond.
