> Execname is a variable in DTrace and not a probe (?), so how would it help with automatically attaching to new PIDs?

You're correct, and I may have provided "a solution" to a misunderstanding of your problem - I don't think the "not matching new procs/pids" is inherent in DTrace, so indeed you might have run into an implementation issue (as it was 15 years ago). I misunderstood you as perhaps using a predicate matching a specific pid; my fault.
