-[**Controlled Async Deposits**](https://github.com/ERC4626-Alliance/ERC-7540-Reference/blob/main/src/ControlledAsyncDeposits.sol) reference:
-  - yield for the underlying asset is assumed to be transferred directly into the vault by some arbitrary mechanism
-  - async deposits are subject to approval by an owner account
-  - users can only deposit the maximum amount.
-  To allow partial claims, the deposit and mint functions would need to allow for pro rata claims.
-  Conversions between claimable assets/shares should be checked for rounding safety.
