This does indeed point to one missing functionality:
an "inferior-comint-minor-mode".  I.e. a minor to use in source code
buffers that provides the usual bindings to send commands to some
underlying comint buffer (like C-c C-l).

M-x run-<foo> is the standard name used.  I don't love it because it
breaks the "prefix all functions" convention, but it's been around for
a long time.
