I was also thinking in addition to json, that it might be useful to have
an optional ncurses top-like mode in ss. The level of detail could be
unfolded for a specific entry on demand, etc. I would not add it as a
hard library requirement, but in case ncurses headers are detected by
the configure script, it could be compiled in then. It's also easily
changeable since there's no such requirement that the way data is being
displayed needs to be stable for scripts.
