Just about everyone has disagreed vehemently with you about this, in every of
the last 5 releases or so.  I don't think it's ok that you continue to ignore
that.

I find this policy so depressing that I stopped even opening the release
notes, just to preserve whatever semblance of sanity I possess.  I'm know I'm
not alone in that.
