Funny thing is, the exact same argument was made for fourth edition (which, in the preview, had numerous feats like "Purple Phoenix Power" that gave zero indication of what they actually did) and most people concluded that there is a clear difference between a name that's a real word with a meaning you might not know (e.g. "hook" or "lucubration") and a name that's completely meaningless (e.g. "viper strike").
Anyway, a certain level of hyperbole is acceptable (e.g. a millipede does not actually have a thousand feet, it just has lots of them) but spells/maneuvers that really don't do what they advertise are problematic.
For instance, consider a divination spell that fluffs "this spell lets you find exactly the item or landmark you're looking for, wherever it is", and that in reality lets you ask three yes/no questions about said item and that's it. This spell clearly doesn't do what's advertised, and that bothers certain people. I'm sure it doesn't bother certain other people, but if WOTC is really trying to appeal to as many as possible, they should clearly avoid this.
