I fiddled around a little bit this weekend and confirmed that this (sloppy)
code makes highlighting work for all shell types that sh-script supports:

;;A quick hack to try and support more shells syntax highlight in org babel
(require 'sh-script)
(require 'ob-shell)
(let ((shells (seq-filter (lambda (shell) (not (eq shell 'sh)))
(flatten-tree sh-ancestor-alist))))
  (let ((toAppend (mapcar (lambda (shell) `(,(symbol-name shell) . sh))
shells)))
    (setq org-src-lang-modes (-distinct (append toAppend
org-src-lang-modes)))))

I'm a relative newcomer to elisp, so comments and suggestions are welcome.
This is basically what I meant by "dynamically amend org-src-lang-modes
based on the contents of sh-ancestor-alist".

Thanks,

Derek
