The main reason is that designers are not even aware of the techniques. You can get CS degree that includes compiler work, and have a head full of LALR(1), without knowing anything about the Lisp approach.
In my Alma Mater, at the time, there was a third year course in programming languages that had Scheme exposure. The follow-up fourth year course in compiler construction was all C hacking with Lex and Yacc, and that was that.
I was able to wriggle out of taking the prerequisite, too.
