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.
http://blenderartists.org/forum/showthread.php?342262-Cycles-ID-mask-looks-low-sample
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.
Changed status from 'Open' to: 'Archived'
Actually, this is intended behaviour: http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Passes
"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.
