Named spells become increasingly absurd the moment you have anything casting it naturally or from a patron.
4E witches and 3E sorcerers, for example.
Named spells should become increasingly re-flavored the moment you have any character casting it either naturally or from a patron.
A hearty witch could reflavor "Tasha's Hideous Laughter" as "Merry Be" instead, and then the original name wouldn't matter, because the player wouldn't have used any part of it anyway.
Having an attribution to an "originating" character as part of the name of some spells helps to strengthen the message that magic-users can create new spells, or create new versions of old spells.
