Though just because photoshop does it that way doesn't make it the
best way.  It seems to be a hugely confusing area for ps users, too.

It wasn't until I started digging into the PDB that I discovered that
channels are just greyscale drawables, and handled as such the

I think that all of the "channel" use cases should be examined before
deciding how these should act.

My own experience with channels is limited to:
1) Image decomposition for masking/converting to greyscale
2) Saved selections

Possibly because that is all the gimp documentation talks about...

In the glossary,
http://docs.gimp.org/en/glossary.html#glossary-channels and
http://docs.gimp.org/en/glossary.html#glossary-masks it refers to
these two uses.

Sven mentioned other uses, like spot colour and halftoning.  I can't
find any references on using gimp channels for spot colour, in fact
google only finds me claims that a weakness of gimp is that it does
NOT support spot colours.
