Why it relates to major mode,

Currently, with :noweb-prefix set to yes, the above code will be expand to
#+begin_src elisp
(let ((a 0)
(let ((b 1))
   `(,a ,b))
#+end_src

~(let (~ is the prefix of <<varable-bindings>>.

I thought we can replace just the prefix in current code[1]  with
~(setq prefix (replace-regexp-in-string "[^ \t]" " " prefix))~ ?
