@SpicyLemon has made a similar PR 14224, and left some good comments in issue 14701, thank you. I agree there is no reason to have separate before/after hooks, and I agree PR 14224 behaves similar to a BeforeSendCoins hook.
I still made this PR because:

1. This is a more generic hook, which not only does sendRestriction (I know it's just a name)
2. In our use case, it makes sense to do it after SendCoins because if SendCoins fails, it can revert earlier without wasting time in hooks.
