Is your feature request related to a problem? Please describe.

If your installed version of baseline-browser-mapping is greater than 2 months old, you will receive a console warning advising you to update to the latest version.

This warning is blocking us to run CI pipelines on older builds.

This violates the principle of reproducible builds - we need to be able to reproduce any build from the past and have the exact same output each time.

Besides that, it's also really annoying to have to constantly update this package when all we care about is nodejs features which rarely change.

Describe the solution you'd like
Provide a way to opt out of (or better: opt into) this feature.

Describe alternatives you've considered
Difficult to find alternatives when Babel.js depends on this package.
