I would not be willing to implement this operator in NetBSD make since
it would only be an alternative spelling for ':=', and I don't see any
value in that.

I never really missed this operator.  What are your use cases for it?

neither mentions the operator '+=' nor the operator ':=', so why do you
think the combination of these two operators should be standardized?
