I learned never to use autoinc IDs in anything especially not URLs where they leak DB info, etc. However, I've seen it many times where younger devs do exactly that because they're learning from bad online books or tutorials. Every generation dev needs to relearn the same lessons. I also suspect that many devs today are learning platforms first and software skills last. This was the reverse for many devs that came from building it the hard way and then using platform tooling to simplify. Newers devs are looking for the tooling to provide the core skills guardrails.
