Sure, if it comes to that being necessary.  Otherwise, I'll opt for late 
loading whenever possible.  AFAICT, none of my machines are members of that 
"few".

I don't know.  I suspect there's a chance Intel *may* start publishing a 
Changelog.  It really need not be so detailed that it reveals "trade secrets".  
And I could make-do with a report that certain updates *do* mitigate Spectre.

Intel has withdrawn some of the updates because they caused new problems.  
Updating microcode can be a dangerous thing.  I've never found a need to live 
on the bleeding edge of technology.
