Yes. And wouldn't it be appropriate to have the same ability when you want
to update your system to the next version?

Fundamentally different? Where? Both are mechanisms for distributing code
and whether a package contains a self-contained set of changes or not is
really up to the maintainer. For example, SmaCC requires the RB parse nodes,
Jacaranda requires Connectors. Where's the difference?

Most of the confusion of new users come from obscure UIs...

If you're okay with pulling in Connectors why is it so problematic to you to
pull in a version update? In both cases you get "more than you want" and I
would claim that in both cases you should therefore get an information about
what is going on. For example:

Jacaranda vX.Y requires the following packages to be present:
	* Connector (vX.Y)
	* SqueakUpdate (vX.Y)
Do you want to load these?

The system tells you what it is going to do and it's at your disposal to
take it or leave it. To me, that's clearly an advantage about not being able
to load Jacaranda at all, don't you think?

But that's entirely unrelated to what I was saying. One is the issue of
hosting Squeak version updates at SquakMap (which I was talking about) and
the other is the ability to have update streams for each package (what you
are talking about).
