    Yes, it would obviously need a hook so that modes like Lisp, Python, C, ...
    can provide a more precise definition.

These modes already provide a completely precise definition,
in TAB.  I don't see any case where I'd want to use this command
in such modes.  The cases where I do hand-modification of the results
of TAB almost always have to do with how to align the inside of
a construct; going back to the top of the construct is always
too little.

However, we need not argue about that; I agree the command is useful
for other modes.
