What I mean is the "holy grail" of white box or x86 + home-grown or
new/cheap NOS.
Running a traditional vendor's OS on a white box or x86 isn't going to
necessarily be cheaper from a licensing perspective.

I'm not talking about their in-existence... I'm talking about the wide
difference between getting these "intend-based" solutions standardized,
and what is actually happening that hasn't been shared, and/or is
proprietary, particularly with the cloud bags (bags = boys & girls).
The otherwise untidy standardization process for "SDN" does not mean
operators (including the cloud bags) aren't enjoying their own
"automation" deployments, whatever those may be.

Like I said, "if" and "could". I don't know...
What I know is the cloud bags have the resources to experiment and write
code, maybe even to a larger extent than the traditional vendors they
buy from. Sure, the problems you mention are not unlike what we see
coming from vendors where the person interpreting the RFC to write the
code has no idea what IS-IS actually does. That comes down to staff
management, so not an entirely big problem to solve once they have the
right leadership.
For my shop, it still makes sense to rely on a traditional vendor to
solve my networking problems. This isn't necessarily the case for
fast-growing cloud bags, or network operators eating up the
"intent-based" liquorice :-).
Mark.
