As the sibling comment from eximius mentions, devs will routinely reach for these long before they’re remotely needed.

A well-tuned Postgres installation on fast hardware and intelligent schema design can scale incredibly far, even if you’re asking it to double as a message bus and full-text search tool.

Maybe I'm lucky, but I've not seen this. Sure I've seen this from junior developers who aren't thinking through the actual requirements they have, but I've not seen it on a team with any real level of experience.

I have seen many cases of people decrying the use of some of these without understanding the requirements though. People with strong opinions like to make up their own requirements without necessarily listening to the business, considering the team, considering the existing solutions, etc.
