All of these roots were already accepted in the Microsoft root store.  
Microsoft recently relaxed their three root policy provided that the CA can 
show a need for additional roots or that the CA has a root migration program in 
place to keep the limit to three.  Because of the communities we support, they 
permitted us to include five roots.

Jeremy, not that I overly care, but are  you saying that all these roots plus 
the existing roots were accepted in the Microsoft roots program? I thought 
there is a hard limit of three roots these days and if correct and enforced by 
Microsoft your argument doesn't hold.

I'd say that you probably should have not more than three roots, maybe each 
with a particular algo and hash. From those you can and should issue 
intermediate CA certificates according to the various purposes you outlined in 
your mail.
