I'm assuming the said boss would not have approved the update to GNOME without first checking that all the features they require the workforce to have in order to work, are present.

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".

When you cook, do you just give people a bowl of nutrient paste, saying "that's all you need to remain functional"? But we'd like something with texture and flavour. "So what, it's not like those things are needed to be functional. You can get by without them."
