In June 2025, Conor Sheehan improved the command-line interface for the mozilla/gecko-dev repository by removing the unused --push-to-lando flag from the mach try command. Using Python and leveraging skills in build tools and code refactoring, Conor consolidated the default behavior to always push to Lando, eliminating related warnings and reducing unnecessary CLI options. This cleanup aligned the tooling with established workflows, minimized potential confusion for developers, and reduced support overhead. The work demonstrated a focused approach to simplifying developer experience by streamlining command-line interactions, though it addressed a targeted area rather than introducing broad or complex new functionality.
