Yeah, given Intel's support for TXT and SGX which are basically moves in the opposite direction, I highly doubt they want to lose customers over things like not being able to play some new DRM'd content from Netflix. The gain from this is probably minimal compared to the loss from something like that. While I'd definitely buy it, the market potential of it seems limited overall.
Though it's possible they could just offer it as an option on some chips to get both markets which would do the job, but given the sheer diversity of ARM and possibly RISC V SoC vendors, those might be a better starting place than x86.
