I suppose that some users think it's nice to have the graphical
point-and-click features of Gufw, but plain old ufw from the command line
is so dead easy to set up one hardly needs the graphics. Basically all you
ever need to type is:

ufw enable

or

ufw disable

Once enabled (or disabled), it remains in that state through all future
reboots, until you feel like changing it, which I never do (it's always
enabled on my machine). So at least for me, the "G" in "Gufw" is of no real
value and won't be missed if it gets axed because of it's systemd
dependencies.
