Simple answer, most of the time no, it doesn't..
It really depends what are you doing and what you expect from it. For general purpose work, Keysight, Tektronix,Keithley, Siglents and Rigols are overkill most of the time, and even simple cheap PSU will do.
Many people have old linear PSU-s too.. If you only simply power circuits with it, many circuits are not very sensitive to power quality.
On the other hand, some sensitive circuits are very picky about power. So picky, in fact, that you have to battery power them...
So it really depends.
If you think you will use it as a precision power supply, than again, that job is more adept tu SMU units...
Also do you want to control it remotely via some program or script ? For that you need one with good connectivity.
