I haven't! I literally never think about these things because they are literally never problems. It's frustrating to see people suggest that such things are intrinsically problematic because they have misused, or witnessed them be misused, without recognizing that they are not intrinsically worse or better than alternatives.

I've witnessed severe, horrifying problems, absolute nightmares, due to misuse of serial/bigserial. I'm not here trying to convince anyone not to use them. Right tool for the right job and all.

The argument here reads to me akin to suggesting that, a baseball bat is not very good at cutting loaves of bread! don't use baseball bats! you should really stick to knives!

Can we perhaps just agree that it's both possible to hold knives without cutting yourself and possess and wield a baseball bat without ruining your sandwich?

Anyways, at this point you're just posting flamebait and I don't particularly enjoy the direction the thread has taken by pulling credentials and implying inadequacy. It's not constructive. I hope at least some readers are convinced that they need not fear the UUID.
