There's a phenomenon I think of as revenge acrostics. This isn't that. But it's in the same ballpark.
"Hooke, for example, when he figured out how arches work, published it as an anagram. He condensed the idea into this pithy statement: “The ideal form of an arch is the form of a chain hanging, flipped upside down.” Then he scrambled the letters to make an anagram and published it. That way, he wasn’t giving away the secret, but if somebody came along a few years later and claimed that they’d invented it, he could just unscramble what he’d published."
(Neal Stephenson, Some Remarks)
