A quality RenderID type of output

unfortinantly I dont see any other way, then those already intergrated. Yes multimatte is a bit of work. But you get a nice and clean RGB selection.
How would you imagine a way to do this?

The only plausable way I can see at this point is to tag each object with a number. Then store it’s separate alpha with that number whilst other objects would be occluding mattes. That is possible to code in for sure. However, there is a new problem which would arise at that point: which packedge can read such format or extention of format?
you see…

I like the idea of extra alpha channels for different objects !! It would be ok as a render element, so every software would be able to read and use it at mask. We currently
use Vray_WireColor for selecting individual objects with antialiasing. Works in most cases.
But extra alpha channels would be nice and more flexible.
