I've personally worked on a Lisp backend, it was probably worse than most of the JS sites you lament about. Of course, it's probably not Lisp's fault that that project was a mess, but the ultimate level of flexibility that CL provided let bad ideas worm their way down to the compilation level, making it really hard to work your way back out. Honestly, you've never felt tech debt pain like unwinding reader macros.
