feels misleading because

• being inside a multicall does not guarantee that it’s safe, it should still not leave tokens on the contract
• being outside a multicall already prevents calling this function (because the default initiator cannot transfer funds)

Additionally, we should consider documenting that some other functions (notably the Morpho functions with callbacks) are well-suited to be called directly

Do you have a suggestion for another phrasing?

I don't feel like the current wording makes the reader think that calling this function can be considered safe inside a multicall. It only highlights that this function is not intended to be called outside a multicall, even though it may not even work outside a multicall
