It's the inner platform effect. When I was young I fell into the same trap. I invented a flexible database schema where I put each field into a database row with some metadata describing the field. But that's nonsense. Just use what the database provides.

There's a Wikipedia page about it: https://en.wikipedia.org/wiki/Inner-platform_effect

A variant of it is: Any sufficiently complicated program contains a slow and buggy implementation of half of Lisp. That's the Greenspun's tenth rule: https://en.wikipedia.org/wiki/Greenspun%27s_tenth_rule

This applies to the kernel as well to put it bluntly and a bit ironically: eBPF, but this shouldn't be understood that I mean that eBPF is not well thought out! https://en.wikipedia.org/wiki/EBPF
