If cameras shot at 24 dead and then played out on an NTSC system, they would have to drop the speed by 0.1% or do frame rate conversion by means other than 2:3.

I know, but hasn´t this been done for decades with 24fps film? The only difference is that the HD camera shoots at pull-down rate directly instead of doing the pulldown during telecine?

What I meant was why not do the entire post at 24.00 and ONLY pull down the image for NTSC media (TV, DVD).

Since BD, DCP, prints etc. all support true 24.00 why force the entire post-chain incl. camera-speed to 23.98 if only a small part (and even smaller in the future) of the release media can only play 29.97?

Why "terrorise" everyone with pull-down confusion for a future niche product. Why not do the pull down at the end only for the media that needs pull-down?

(Speaking strickly of theatrical film here)
