imho, that depends on whether or not the grand design of being able to
   run "foo -M netbsd.0.core -N netbsd.0" on dead kernels has now been
   completely abandoned.
   
   say it ain't so?

why does it depend?

	- kvm grovelling of dead kernels will always be supported in
	  NetBSD as far as i can tell.

	- permenent removal set-id bits will always be supported in
	  NetBSD as far as i can tell.


(of course, quality is always an issue).
