I'm dating myself a bit here, but I'm reminded of Douglas Crockford's book, JavaScript: The Good Parts. The idea being that under all of the cruft and foot-guns, JavaScript actually had all the elements of a good language. You just had to be disciplined about using only a subset of the language.

Isn't that essentially what we get with frameworks? I'm still unconvinced that frameworks are a problem with agents. If anything, pointing an agent at a single framework reduces its API surface, compared with the standard lib and every permutation of possible solutions that comes with it.
