I think Microsoft’s Trusted Root Program [1] is still important even with Edge moving to be a Chrome derivative, and it being missing in the announcement is interesting given three other major programs have approved for inclusion.
Inclusion into the trust stores for Linux distributions like Red Hat and Ubuntu will be another interesting one to watch with Certainly.
Oh and the Oracle Java Root Certificate Program [2], since the JRE has its own root certificate store, and Java is still used very broadly.
