I already use UUIDs for various fields and didn't want the id to be confused with other fields. More of a clarity/style decision than technical.

Unfortunately this means you get to make the same mistake as originally made with UUID: the static machine ID is a privacy leak.

Is it? Not sure private ips are so sensitive, esp. the lower parts.

If it’s unique it’s a privacy leak. I’m not going to debate that, it’s common knowledge.

UUID was changed in the 90s to be a hash of this instead and later to just be a completely random number because there are so many bits the likelihood of a single duplicate being generated before the sun has swollen enough to consume the earth is slim so you don’t actually need these schemes to provide a unique number.
