Completely agreed. Not sure what the historical reasons for lsof and ss are, but unix tools are structurally in a hard place when it comes to having sensible defaults over the long term.

Generally speaking, you can only have sensible defaults over time if you're able to change the defaults over time. New users and new use-cases come with time, and so what constitutes a "sensible default" changes.

However (and this is a drum I like to bang[0]), because unix tools only deal in usually-text bytestreams without any higher level of abstraction, consumers of those tools end up tightly coupled with how output is presented. Without any separation between data and its representation, the (default) representation is the tool's API. To change the default representation is to make a backwards-incompatible API change. A good example of this is how ps aux truncates longer than like 7 characters.

Hah yes, I've come to unashamedly - by muscle memory since the 1990's - find myself always typing 'ps auxw[w...]', where [w...] is some arbitrary number of w's depending on how heavy my index finger feels at the moment of typing.
