Sorry, but I have no clue what the above is trying to say.

The original 's--h config <name> [<value>]' is quite understandable.  It
is like "git config <name> [<value>]", i.e. either get the current value
for the name, or  set a new value to the name.

What does this 's--h config --stage' that does not take any option
do?  "git add .gitmodules"?  Something else?  In what meaning is the
word "stage" used?  Is it used as a verb "to stage"?

In a series that lets us use the data in the .gitmodules file without
materializing the file in the working tree, I would have expected
that you would want an option to specify which .gitmodules among
(1) the one in the working tree (i.e. the only option we currently
have), (2) the one in the index, and (3) the one in the HEAD, and
when I saw the title, I would have expected that

	git submodule--helper config --stage name

may be a way to read from the .gitmodules in the index to find the
value for name (however, we we follow the option naming convention
in gitcli.txt, it should be called --cached, I would think).

Again, a claim without explanation or justification.

If you are planning to something like

 - prepare trial contents in file
 - do whatever "additional checks" on
 - add the contents to it to the index as a new .gitmodules blob

Then you do not need such an option.  "submodule--helper" is purely
a helper for scripts, and not for human consumption, so scripts can
just hash-object the blob contents out and update-index --cacheinfo
to register the blob at any location of choice.

But as I said, this step is way under-explained, so my guess above
may not match what you really wanted to do.
