Mostly due to interest in FP being driven by intrinsic desire to use it, since it's so rare in enterprise. Anyway, a lot of that discussion filters down into more popular languages, so it's pretty incorrect to think of it as all academic junk or something.

It is much less of a problem with OCaml than most non-OCaml users would expect. OCaml isn't Haskell; if you want for loops and similar generic imperative features you can have them!

Save for Erlang and Elixir, this tends to be the case with ML-family FP languages, not so much with LISPs, in my opinion of course.

The problem is there is no middle ground. FP people forget about the product because of FP. Alot of non-FP people forget also forget about their product because their are swamped with unecessary maintanence. There is a middle road in there somewhere where you use just enough FP to avoid the problems you would face without it, without getting totally sucked into making it perfectly consistent.

You've been misimpressed :) Clojure/ClojureScript, Elm, Erlang/Elixir are examples of pragmatic communities and cultures.
