Why does the implementation of CreatorToken (ERC721C) return false for isViewFunction?

[nix-eth]

I have never seen this return false in other implementations. And the deployed validator contract function validateTransfer is view. Mostly curious why this is, seems intentional because unit test covers.

seadrop/src/ERC721ContractMetadata.sol

Lines 300 to 307 in 347d58e

	function getTransferValidationFunction()
	external
	pure
	returns (bytes4 functionSignature, bool isViewFunction)
	{
	functionSignature = ITransferValidator721.validateTransfer.selector;
	isViewFunction = false;
	}
