That would be neither prudent nor practical.

Perhaps you did not consider the consequences. What if it is compatible with your 
processor? Would you send me a handwritten thank you card if that processor stops 
processing? Would you be a happy replacement-sale customer of Intel? I think you did not 
put much thought into why we are talking about it a year later or at all.

Unlike the now-oh-so-scary feature that was in existence for decades, that is only so scary 
because of a "clever" idea to "cloud" host different customers on bare metal, without any 
consideration to their security, this could affect real people not just oh-so-clever computer 
farmers.
