Should Microsoft allow x86 applications on WOA

I'm wondering if Microsoft should give in to allowing developers the ability to recompile programs for WOA? Would that be a good thing? And if they do should Microsoft start pushing a desktop Metro design as a requirement (because it may show up for Windows 9). I think part of WOA's attraction for ARM chip makers is the ability to get their chips on Ultralight notebooks and PCs. But I also see quite a few people who like Windows 8 but were hoping for tablets based on Windows Phone. Finally there's Microsoft who I think want to start fresh with WinRT.

Thoughts (Please be civil I have a tazer)
