You joke, but the first place I saw that happen was in GNOME. Personally I would prefer the application name to be central with the description subdued (basically reverse of how they have it in MATE, which is the limit of my current GNOME experience).
Whichever way it's done, I will say it's better than just the application name. Even better though, the files that govern what is displayed are easily (and very often are) internationalized. Eg, when you have your language set in English VLC might say "Media Player" but if you select Esperanto it might say "amaskomunikiloj ludanto" or whatever (google translate, there) - meanwhile "VLC" means nothing to someone who doesn't already know what it does.
