Thank you for engaging with our community in this way, I think it's 
beneficial to all concerned. Please don't take the following question as 
anything other than genuine curiosity, in the spirit you describe above ...

I'm curious about why MS chose not to simply implement the Happy 
Eyeballs protocol? While I think that the approach you describe does 
indeed have merit, it also has a lot of "issues," especially during the 
current transition period where a successful IPv6 connection today might 
not be so successful tomorrow, or even an hour from now. The HE protocol 
was designed to take sporadic problems into account, and provide the 
best overall user experience for all sites, with a slight preference to 
v6 transport. If there was something we missed in designing that 
protocol which caused MS to go a completely different direction I think 
it would benefit the community to know more about what when into that 

Best regards,
