StarlingX does have time built in for this testing, intending to be
complete before the STX 2.0 release at the end of August.  I've
suggested that we need to test both Train and our Stein backport but I
am not the one with the resources to allocate.

Oddly enough, in my $OTHER_DAY_JOB Intel's new Third Party CI is at
the top of my list and we are getting dangerously close there in
general, but this testing is unfortunately not first in line.
