It's a long list. It gives you runtime parameters as well as the stuff you configured in your unit file or which was implied form the defaults. It is also sometimes a little bit too much for people to grasp, since for example it shows the full set of dependencies that are implicitly added to most services. We certainly don't want to show this to our users most of the time. So, "show" is very verbose. On the other hand "status" is pretty short. It only shows runtime information and that in a hightly reduced way. For example fields are suppressed depending on the state of the unit and other fields are shown, and then shows the process tree for this. It also ellipsizes and aligns the output, and applies coloring (in case the unit is in some 'maintenance' state, i.e. crashed, exited with non-zero exit code, timed out, yadda yadda). I think the differences between the two commands are sufficiently big to warrant the two seperate commands. > Having "status" and "show" give the same info in different formats will > always be confusing.

You are discussing something you never actually played around with... Trust me, the output of the two commands is sufficiently different to not confuse anybody.
