Is supporting both P4 and NPL like mixing water and oil?

I was talking to a friend on their options for a multi-vendor strategy. He said, “it is like mixing water and oil”, talking about supporting common interfaces to multiple vendors. For the record, I am biased towards both P4 and NPL, possibly building the first ASIC based P4 switch on Doppler, and having contributed to NPL made me connect with both. I delved into minute details of both languages and architectures. There are practical challenges and opportunities in bringing these languages together.
