When we were firming up the constraints idea in Vancouver, if my
memory is correct (which it quite often is not these days), part of
the long tail Robert suggested was that once constraints usage in
the CI is widespread we could consider resolving it from individual
requirements lists in participating projects, drop the version
specifiers from the global requirements list entirely and stop
trying to actively synchronize requirement version ranges in
individual projects. I don't recall any objection from those of us
around the table, though it was a small ad-hoc group and we
certainly didn't dig too deeply into the potential caveats that
might imply.
