The way I interpret the PMS, this success is not expected:
the atom ">=app-misc/dummy-slave-1" matches the cpv "app-misc/dummy-slave-1"
which does not contains the use flag 'static-libs',
and thus I expected a 'missing use flag' error.
I'm not suggesting to change the behavior of emerge, I'm saying that:
- the way I read the PMS, I expect behavior A, but in practice, I see behavior
B.
- what does the portage devs / PMS gurus think about that?
- is my understanding of the PMS wrong, and it actually says "behavior B is
expected"?
- if yes, where did I fail in my understanding?
- if no, should emerge or the PMS be updated so they both describe the same
behavior?
- I will implement your ruling in my tool, which I try to match as closely as
possible to the PMS

The way I interpret the PMS, this failure is expected.
I'm sorry if I'm not always clear, I try to be, and many thanks to take the
time to answer my (unexpected and strange) questions.
Best,
