that may be true, however a *description* explains something and
is by definition verbose and probably long and leads to linebreaks

a name is normally short

no

by logging unit's name if you really have no clue about a service
you can do "systemctl status servicename" and see the decription

but that don't happen often because:

* most unit names are pretty clear
* you should know about services running on your machine
* at least after "systemctl status" you know anyways
