| I think the usual convention is to use multi-part when you have multiple camera views, each of which needs the same set of channels (e.g. right and left eye, each of which have R, G, B, A, Z, etc.). But when you simply have a lot of distinct channels from the same camera (such as various lighting AOV's, as you mention), then usually it's done as a single part, with lots of channels named appropriately.
It would be great to have the possibility of sharing
a z channel between parts. For each framebuffer (diffuse, indirect
etc) we write out
a part and we have to include the z channel which is identical for
all parts.

Indeed, there was quite a long thread about that in

still have that saved off somewhere, but it might take a while.
In short, we wanted to have some commonality between parts
to ensure that there was some semantic that bound these parts
together which would prevent a free for all mash-up. I seem
to recall that the stereo pipe was good test case for things
like display window, time code, aspect ratio etc ...
There was a desire to have a small enough set that could be
potentially relaxes as time went on; going the other way is
much more tricky.
