The old names will remain in synonymy so they don't get lost. So what is the point? Also renaming a species can sometimes be a lot harder than people imagine. The name of the species places it a taxonomic tree and when there are disagreements (e.g. someone may have been unsure and simply identified the specimen to genus level). If the whole genus is renamed (e.g. Hibbertia) then it's not a particularly hard problem to solve, but if something goes from, say, subspecies to species with a different name it's an enormous amount of work. And what for? The original name will be retained as a synonym anyway
