I doubt you'll miss the languages but plenty of people use the drivers all the time, it's definitely not something to just throw away if you work in a professional environment, etc...
i had to uninstall the gimp print drivers so i could print borderless over firewire with a specific driver for my printer, being a professional photographer it was necessary to do this so i could have a complete colour managed workflow (and print borderless).
