That's good to know (I was worried the device would not be detected as
supporting discard because it doesn't report lbpme and doesn't declare a
conformance version (see below)). Is there a tree with all these updates
in or do they need to be pieced together from this email thread?
Additionally is it worth quirking sd_try_rc16_first on when
BLIST_TRY_VPD_PAGES is present?
