Yes, the "do people care" filter is what I usually use.  When new
functionality is added, we usually mention it because someone usually
care, but for performance, the threshold is usually whether workloads,
even rare ones, would have a visible performance change.  It is
difficult to determine this from the release notes, which is why I
always need feedback on these items.
