Since there is on no roadmap, an indication that this bug shall fixed ... Here a reminder!

The ID pass has no grayscale values, that makes it unusable for compositing.

Any Workaround (e.g emission material override) is really a bit frustrating and time consuming.

It must be possible (however), to create a clean black and white mask otherwise the Cycles ID passes are useless.

Please Devs, fix this existentially feature!

This bugtracker is *not* for feature requests. Therefore I set this to a ToDo task now.

And as already noted by someone in the Blenderartists thread, the missing AA comes from the fact, that the ID passes are only rendered with 1 sample.

"The Z, Object Index and Material Index passes are not antialiased. This is done because such values can't really be blended correctly. "

Thanks Thomas to set this to a ToDo task.
