I think this sentence from the section you linked is meant to express
that:

  You will find a description of non-core porcelain configuration
  variables in the respective porcelain documentation.

but it is rather opaque, isn't it? You did not know it, but your hook is
a non-core porcelain. :)

I think it could probably be re-worded, and possibly even indicate to
authors of other programs that they are free to make up their own
variables (but should take care with namespacing them appropriately).

Would you like to try your hand at writing a patch?
