I'm not sure exactly what you disagree with.  The feature "configuration
file" is certainly operating as designed and as documented.  If you want
to propose an additional feature, then you're free to do that, but there
is no way we'll let client programs read the server's configuration file,
they just don't have a business there (if they can find it at all).

If you want to change the location of the local socket file for both
client and server then you can make it a compile-time change.  The primary
reason for it being a run-time option, too, was for "virtual hosting"
setups, and in that case it's doubtful whether a global client-readable
configuration file would even be appropriate.
