About generation numbers, please have a look at the thread leading to this

In short, generation numbers were not such a good idea because there were
already existing ways to get around the problem and because there was no
simple way to implement them without breaking other things.

Thanks for the interesting read, Christian.  I didn't follow the
discussion closely, and only have a passing understanding/ interest in
the issue.

My opinion is that your proposal can only be accepted if it is also a
solution, or a big step toward a solution, to other difficult problems, like
for example narrow/subtree clones.

Hm, a link object referring to a tree object, as opposed to a
revision.  I'll think about this for some time.

So you should try to improve it by looking for other important features it
could provide in a simple way.
This would prove, or at least be a good sign, that it is a fundamental
improvement to add a link object the way you describe it.

I'll look for more submodule-like features to strengthen my case.
