Charlie Marsh details how uv reduced its binary size by over 40% since July (57% on Windows), saving nearly 4 PB of download bandwidth per month across public mirrors. Biggest wins: panic = "abort", a single codegen unit, PGO, avoiding monomorphization on heavy types, and a custom DebugNoInline to stop derive(Debug) from inlining huge error enums.
