Yes, thank you. Having the "name" option in General seems pointless to
me... Complexity without gain. If the "name" option wouldn't exist,
there would be 1:1 mapping between the path names appearing in PA logs
and the configuration file names, which would be quite nice. Also, there
wouldn't be need to care about making the path names unique after
probing (port descriptions would probably still have to be checked that
they are unique). For those reasons I'd like to remove the "name"
option. Do you have anything against that?

Ok. I'd still like to keep the clear phases of configuration parsing
(structure creation) and probing (removing unavailable stuff). So what
do you think? Your comment didn't really tell me whether you agree or
