ob-shell: possibly missing initiate-session functions?

[Suhail Singh <suhailsingh247@gmail.com>]

Currently (Org 9.7.3), org-babel-switch-to-session invokes
org-babel-initiate-session which tries to invoke
org-babel-<lang>-initiate-session.  On a related note, ob-shell defines
org-babel-sh-initiate-session (and uses it within
org-babel-execute:shell).

However, there are no definitions for org-babel-shell-initiate-session
nor org-babel-bash-initiate-session etc.  This means that trying to use
org-metadown (which invokes org-babel-switch-to-session) on shell and
bash language session blocks results in the following errors
respectively:

#+begin_comment
  org-babel-initiate-session: No org-babel-initiate-session function for shell!
  org-babel-initiate-session: No org-babel-initiate-session function for bash!
#+end_comment

Is this a bug?  If so, does org-babel-shell-initialize need to be
patched to set up function aliases pointing to
org-babel-sh-initiate-session ?

FWIW, I have been using such aliases in my personal config for bash and
shell language blocks and they seem to behave as expected.
