Section: https://docs.substrate.io/main-docs/build/runtime-storage/ (Verify First, Update Last)

In substrate polkadot-v0.9.25 branch (https://github.com/paritytech/substrate/tree/polkadot-v0.9.25) #[transactional] macro got deprecated since it is now default behavior (https://github.com/paritytech/substrate/pull/11546 & https://github.com/paritytech/substrate/pull/11431). So now, even if verification happens after storage update, the state won't persist. It will get reverted on Err. Hence, it makes sense to update that section according to new updates. It is still best practice to follow, but it needs updated information.

Are you willing to help with this request?

Yes!
