Agreed with the "most" sentiment. But it is worthwhile for anything where a misunderstanding is possible and the consequences of a misunderstanding would be meaningful (to you).
When I was first dating the woman who became my wife, we decided to take a vacation together and split the expenses. We worked up a budget and did a pretty good job of sticking to it, until our car had a minor issue and we had some extra expenses (an extra meal at a restaurant, etc.) When we did the numbers at the end of the trip, it turned out that I overpaid by a bit, and she wrote me a check for that amount. When I cashed it a week later, she got very upset with me, because she forgot about it and already slated the money for something else. My response was "well, you gave me a check and I simply cashed it. I would have gladly paid for the extra stuff, if I knew that's what you wanted". Her issue was that something unexpected happened with her money.
Long story short, a quick text with "About to cash the vacation check you wrote" would have saved us a fight. OTOH, coming up on 10 years together, so I think it worked out OK.
I'm curious if something like this would happen today. With PayPal, Venmo, Interac E-mail Money Transfer, and other similar services, I would expect such a transfer (if the other person felt obligated to make one) would be nearly instantaneous.
I was referring to the specific case of having a significant other.
I think that the protocol as described makes a lot of sense, because paperwork. (Although I think Clerky was supposed to be trying to help out with that?)

You bastard! She forgot and you cashed it anyway! haha.
Handshake deals are reliant on trust, which friends/spouses usually have in good supply. This protocol is attempting to add enough formality to lower the trust required somewhat (because people have been welching, so enough trust is not always available), without dropping it all the way to zero (which is what a traditional antagonistic/defensive contract is for).
