Haven’t seen even something like opinionated frameworks work well with their initial abstractions.

Even file interfaces in most programming languages don’t come with pipelining. Most are leaky abstraction.

Most abstractions also deal with 1 thing instead of N things. There’s no popular http server that supports batch request processing.

Async-await is a plague of an abstraction.

Abstracting something like trivial if statements is not a problem. The best transaction of all, passing a function to a function is underused.
