So after last week’s discussion at the F2F, I will close ACTION-2949 (to
unapprove the test) without doing it, and we will leave this test in the
implementation report with a note to state that the WG is happy with it,
and that other implementations not otherwise represented in that
document, like ASV, pass the test.
