Thanks for your very to-the-point answer!  I'm still disturbed by the
above statement, though, because not being managed by CFS does not imply
having no meaningful priority: RT tasks seem to have one.  Did you mean
to imply this?  Guessing not, I added your answer with code illustrations 
as https://unix.stackexchange.com/a/436575/119808.
