Ideally of course we would test as much as we can, but this isn't a 
technical question. Even Github has limits on how much workload it can 
handle so if we enable more platforms we may experience delays that are 
more detrimental overall than the impact of limited testing. I don't 
know who may know about the internal details here - @shipilev?
