However, "choice is poison" is a rather extreme over-compensation for this problem. Sometimes, options really do provide value. And many times, if they are designed correctly, they don't substantially increase cost; if the features are orthogonal and implemented independently, the additional complexity is only linear with the number of features, not quadratic or worse as happens if they are too interrelated.
I understand that we want to get away from the "you need to spend hours customizing your environment to make it usable" approach to design that plagues some open source project, but going to the other extreme and saying that "choice is poison" is just as bad.
(Personally, I do leave my XFCE4 desktop on default settings, but I do alter defaults in some packages)
The person in the link commenting "PUT IT BACK EVERY OTHER TERMINAL EMULATOR HAS IT" is more baffling.
Both wanting choice and options, but at the same time not wanting to have to change when there are other options.
Gnome Terminal may (effectively) be the only terminal emulator available to you if you do not have rights to install software or to change default software.
Then yes, they should.
If the boss gives you lemons, you don't go to the lemon tree and ask if it can make lemons that read email, browse NFS shares and change screensaver settings. You go to your boss and say "just-lemons isn't good enough".
I'd rather have something that was well thought through and is internally consistant than a grab-bag of customisation, none of which coexists well - like most linux desktops.
