I was trying to push the "just like trees" to the logical conclusion
in order to see see if it leads to an absurd conclusions, or some
useful scenario.  I do not necessarily subscribed to Jonathan's
"vision" (I do not object to it as one possible mode of operation,
either).

Not my idea.  But Stefan's message I was responding to said that
object database for the superproject is the same as and mixed with
object databases for the submodules, so it is plausible that push
always happens at the superproject, and a mechanism to be invented
(I mentioned the need for it in the message you are responding to)
to enumerate all the commits bound from submodules to a range of
superproject's commits would identify these trees to be pushed out.

In essense, "just like trees" folks want to use the gitlinks in the
superproject to only specify the tree from the submodule project
that should sit there.  And my point is that such a world view would
lead to no need for branches in the submodule repository, no need
for commits in the submodule repository, and no need for history in
the submodule repository.  Which may or may not be a bad thing.
