At my company we only use UUIDs as PKs.

Main reason I use it is the German Tank problem: https://en.wikipedia.org/wiki/German_tank_problem

(tl;dr; prevent someone from counting how many records you have in that table)

What stops you from having another uuid field as publicly visible identifier (which is only a concern for a minority of your tables).

This way you avoid most of the issues highlighted in this article, without compromising your confidential data.

I'm new to the security side of things; I can understand that leaking any information about the backend is no bueno, but why specifically is table size an issue?

In my old company new joiners are assigned an monotonic number as id in tech. GitHub profile url reflected that.

Someone may or may not have used the pattern to get to know the attrition rate through running a simple script every month))
