You've put into words something I've struggled with saying for a while, and the exact reason I could never really enjoy working with Common Lisp.
The example I always return to is the lack of pervasive use of CLOS throughout the standard. Something like generic-cl[0] feels like it should be a baseline part of the language. As it is, it's a great library. But people are hesitant to even use it, because the result of making everything generic is a loss in performance!
Of course, [0] talks about optimizations they've done. I don't know how it compares to using the methods in the standard as opposed to the lib. Regardless, these libs only help when writing code, not reading it. Though don't get me wrong, that's a big deal! It's very helpful! But
