Not sure what you mean, you can run XR on a white-box, or x86-host (e.g. cRDP). -that's regarding the disaggregation and NFV...
And regarding the "flavour-of-the-year-SDN-thingy", I guess I could see how it has a certain mystery about it for outsiders, but for someone building an intent based networking/ service orchestration system all the concepts you read about in various RFCs, books and publications are a day to day reality.

I'd say NO thanks very much,
Have you seen what they did with their espresso core? Looks like a bunch of programmers attempt at core network while never talking to anyone with network background, (no wonder their network architect job advert looked more like software architect job advert -not a single requirement around networking design skills). 
There are a few interesting concepts in there worth exploring, but the thing is a mess.
