I agree with many of the points you made but here's another data point on
the topic of bugs --
I watched a presentation  from a couple of guys from Facebook at AusNOG
2016 and one of the takeaways from their talk was that "multivendor is
hard". When you have two vendors, you get Vendor A's bugs, Vendor B's bugs,
and the Vendor A+B interop bugs. In theory this only gets worse with 3+
