clarifications on ERC-3156 flash loan implementation

[BigGod12]

Hi while reading through https://github.com/ethereum/ercs/blob/master/ERCS/erc-3156.md
is it advisable to use reentrance guard for the flash loan function within the contract implementing the "flash lender" interface??
even if the "receiver" contract call back within the onFlashloan to take more loan.. though the transaction should revert if the "REENTER" amount was not repaid but the first initial loan was repaid. since there is two race window "flash loan" that must be repaid.
this blog https://www.rareskills.io/post/erc-3156 suggest using "nonReentrant" for security purposes. but i see no reason for that.
