Out of curiosity, is there any reason why this isn;'t the default? History? https://www.pantsbuild.org/2.18/docs/python/overview/lockfiles#updating-lockfiles

Default switched for 2.19 https://www.pantsbuild.org/2.19/reference/goals/generate-lockfiles#diff

backstory: being careful with a new feature to not break stuff by default.. but could have been more aggressive in making it default sooner.. like, waay sooner 😉
