we don't want external software to include internal details like mlog. slog.Logger is/will be the standard. we still have mlog for its helper functions, and its handler that logs in concise logfmt used by mox. packages that are not meant for reuse still pass around mlog.Log for convenience. we use golang.org/x/exp/slog because we also support the previous Go toolchain version. with the next Go release, we'll switch to the builtin slog.
