I don't know! perhaps in your suggestion there is a bit of ignorance on the subject, maybe you think that this is like one of those MTV awards that are given for popularity , etc. In any case, like any serious award, the Nobel is, but without a doubt it is the most bureaucratic that exists and in a certain way prejudiced.
These qualifications do not take away the value and recognition they have for the scientific community, for example in the Nobel Prize for Physics, where without discussion sometimes prizes are awarded to those who truly deserve it, we must add the literary ones where perhaps it begins to be some overtones of subjectivity, then there are the economic awards where we can begin to have winners where subjectivity grows even more, and so on, anyway getting into the circuit for a nomination is quite complex and full of requirements.
Einstein, for example, would surely have won due to gravitational waves, things that in the end could be demonstrated just a few years ago but he is dead, on the other side are those who should have won a Nobel in life but the arbitrary questioning and bureaucracy to access to a nobel prize are uphill, Vera Rubin is one of those absurd cases that the Nobels have to give a prize to who really deserves it.
This great woman and scientist said these great words when she was asked about why she was never awarded a Nobel Prize and I think they are useful in the case of SN:
"Fame is fleeting, my numbers mean more to me than my name.
If astronomers are still using my data years from now, that is my greatest compliment. "
