Having all the pre-optimized control flow, variable names and comments saves a lot of time for sure . Microsoft won't care quite as much if the 0-days aren't affecting Win10 though, the older OS are basically all out of support period beyond some contracts dealing with Win7/8.

I agree. As long as windows 10 is not affected they will not care.
