There are two large costs that you are ignoring:
a) all vendors wishing to bid for business from A and B will have to
implement and support both solutions.
b) when A buys B or B buys A, the incompatible networks will have to
be merged.
These are costs that run to hundreds of millions of USD, EUR or CNY.
They are costs caused directly by SDOs creating rival solutions.
I think it would be irresponsible of the IETF not to document this
situation. As engineers, we have an ethical responsibility here.
