What is it when you know about the power of features of the "higher level" languages, like generics, but still chose the "blub language" because of other reasons, like ease of hiring devs?

"Worse is better"

or just "Better has multiple dimensions", and not all of them are "Theoretically purer" or "look how succinct I can write this code". "How hard is it to hire devs?" is just one of those dimensions.
