The good thing about "UpgradeImpact" is that it's less subjective than
"OpsImpact", and I think it catches what matters: backward-incompatible
changes, upgrades needing manual intervention (or smart workarounds in
packaging), etc.

Additional benefit is that it's relevant for more than just the "ops"
population: packagers and the release notes writers also need to track
