It would not be good to merge a large kernel feature which kernel
developers and testers cannot test, and regression test.
If testing utrace against its main application requires installation of a
complete enterprise distro from a distro which the particular developer
might not prefer to use then that's quite a problem.
So it is desirable for this reason (and, I suspect, for other reasons) that
systemtap (or a part thereof) be dragged out in some standalone form which
is usable by random mortals.
IOW: I agree.
