If you decide to carry the minimum legal fuel is OK, what is not good is not to be prepared to divert when you feel that your options are narrowing and the enviroment (weather) works against you.
And if you divert then better do it with plenty because you will not be the only one.
I do not want to be patronizing, but these things are know by everybody and that’s exactly why most pilots are amazed that the crew cornered themselves.
Whatever happened during these approaches is subsequent to the fact that the crew had put themselves under pressure because of fuel reasons. It must be very annoying to get those low fuel messages during an approach that needs all your attention.

I agree with you that if you are getting short, you man not even want to try a first shot at an approach. But that would mean you did not consider the possibility at dispatch stage otherwise you would have arrived with more anyway.
