Further, the notation is a "tip of the iceberg" issue; the iceberg is semantics, and I suspect anyone who can grasp the semantics well enough to actually build something, can handle the notation (even if there's a notation they could handle better). Which possibly means - the more notation-capable-but-semantics-challenged people are working in the field, the more work for the semantics-capapble people to clean after them.
