the goal of having more generic markers is still possible and being aimed for - for in-kernel utilization like SystemTap, lttng, utrace, ftrace and similar. The latest iteration of markers looks rather promising in terms of giving us near-zero-cost probe points.
(and last i checked dtrace was not capable of doing something like mmiotrace - so it's a different thing.)
so dont worry :)
