Changelog evidence

The breaking change at dplyr 1.0.0 (May 2020) involving tidyselect interface migration occurred ~6 years ago. The changelog confirms that select_vars(), rename_vars(), and related legacy functions were deprecated in 0.8.4 (Jan 2020) and became defunct/removed by 1.0.0. No realistic regulated research user would still be running 0.9.x (a pre-release intermediate version that never shipped as stable). This window is archaeologically unreachable.
