Yeah it seems so.  That was the first idea I tried and it bit hard my
LaTeX exporting from org-mode. :-(

But I think it should be possible to specify a different shell only for
certain source blocks.  Please consider the customisation variable

   org-babel-shell-names => ("sh" "bash" "zsh" "fish" "csh" "ash" "dash"
   "ksh" "mksh" "posh")

it is possible to modify (amend?) the list of shells but I just can't
find where and how to "define" such a new "shell".

By the way

  #+begin_src shell
  echo $0
  #+end_src

seems to call MS com but

  #+begin_src sh
  echo $0
  #+end_src

an MSYS2 shell /usr/bin/sh...

Probably, I don't want to publish the blocks.  They are intended as a
mixture of documentation for myself and automated scripting for building
Emacs.

Thank you for your interest
