That sounds relatively standard, from what I've seen.
I'd like to think that with the release of OpenEXR 2.0, that we can phase out
the practice of writing a "huge pile of channels" and hope the application
sorts it out with naming conventions, and instead actually use the new
multi-part feature to have a separate part for each pass/layer and a simple 3-4
channel obviously named set of channels within each part.
