#266 removed the https://protobuf.dev/best-practices/api page.
This page https://web.archive.org/web/20250721031945/https://protobuf.dev/best-practices/api/ contained topics such as "Precisely, Concisely Document Most Fields and Messages", "Use Different Messages for Wire and Storage", or "Create Unique Protos per Method", etc., which otherwise may be gathered by watching some of talks given by gRPC developers.
Are there plans to have that information available publicly again elsewhere?
