That may be true of the output, but that's not a very strong argument
against making it much easier to gather and display the LWLock
statistics. I can easily imagine the patch be a useful performance
troubleshooting tool in a high load environment. Depends on how
easy/intrusive it is to enable/use the stderr method on a production
system, though, as well as how much of a performance impact the
measurements have on overall operation...
