Well, CBDCs - if they ever happen - will certainly include a version of such feature. Although it won't be available for everyone, only for government. After all government is there to fix your mistakes, such as sending money to wrong recipient (like crypto exchange) or buying wrong things (too much meat, plane tickets etc.). We can laugh now, but there might be time when such news won't be on 1st April (why am I so gloomy today? 😔).
