In one sense, you're right; I misquoted. The exact verbiage says that "elevated pieces" are disallowed, not "raised pieces."
(https://worldcubeassociation.org/regulations/, under puzzles, heading 3j)
Here is 3j: 3j) Puzzles must be clean, and must not have any markings, elevated pieces, damage, or other differences that distinguish any piece from a similar piece.
Read it carefully.
