Unless there's a special need, they don't fix "bugs" in their ROMs.
Also, for those who played All-Stars first, it was never a problem.
Actually they do, several VC releases got patched, for all sorts of reasons. Some to fix bugs, or change text, others to limit flashing colors. They even dinked with Zelda's intro:
And it's really easy to tell that the flow isn't as natural with the "vacuum" effect. It doesn't matter what you played first. Saying "I played Sonic Genesis on GBA, so I think standing on the air is fine" doesn't mean it isn't a mistake, or poor developer choice.
