It will never end. In science, the answer to any question is always subject to change, contingent on better information.
I always amazed at the angst that botanical names sometimes cause. I've said this before, but perhaps it bears repeating. Scientific names are just made up words, derived mostly from a dead language, describing a concept (the species) that doesn't actually exist.
Taxonomy is really just a mechanism to help us make sense out of a bewilderingly complex world. One of the reasons it works is because the researchers involved have all agreed to play by the same rules. The ability to change names is a critical aspect of those rules. Whether they understand it or not, if the 'don't change anything' people had their way, the end result would be chaos (which is what we had before the development of taxonomic systems).
