Don't worry I'm sure it will work in 5 or 6 years when they get around to implementing this functionality in some subtly incompatible way on each major desktop environment.
Since its impossible to implement something that works across multiple environments hopefully whichever one does the best job of providing this feature also does a decent job of providing every other feature that previously was able to be provided by any app.
