Some users have mentioned that the upgrade code lenses are a little invasive because they are shown per-line. Here are some general thoughts / ideas for how to handle this:

• Don't show upgrades for pseudoversions? Or only for pseudoversions older than some amount of time (1 month? more?).
• Offer upgrades as code actions instead of code lenses. The "upgrade all" could still be a code lens, but this way we could offer more granular updates. Someone may not want to update to a new major version, but they may want to update to a new minor or patch release - code actions give more options.
