Look. You're just wrong. SVN_ERR() always implies svn_error_trace()
regardless of SVN_ERR__TRACING, and there is no additional branch here
in an optimized build (and last time you were introducing those changes
someone demonstrated this via disassembly excerpts).
So, if you want to reduce on branches, then merge ^/subversion/branches/performance.
But as I see it such changes make the code less readable for no gain.
