If somethings sounds promising and or passes the smell test, researchers may try to verify the results independently , with or without peer review
If I'm going to use someone's results as basis for my own research, I really want to know that this is a final, "as good as they reasonably can make it" result, not an "oh we're not quite done with the hard, ungratifying work of actually crossing the ts and dotting the is but here it is" kind of result.
For archival purposes the policy that forbids withdrawal seems to outweigh any other considerations. (I'm sure arXiv has made some exceptions during all this years, for instance if the content is shown to come from a different source.)

Sensibly, that rule was changed.
Conversely some more prestigious/general interest journals like science and nature tend to favor papers based on novelty in a way which often results in them highlighting an interesting problem domain but not a best-in-class method. Indeed they often reject follow up pieces that improve on the published method.
