If we can transfer Amiibo save data to the Wii U when using Amiubo for other games, I could see this not being a really big deal. Inconvenient, yes, like all the fridge cleaning we had to do with the Wii before SD storage was finally updated, but at least we wouldn't have to lose all the data we've worked to create. Ultimately, though, we'll probably start seeing more game-specific Amiibos. This first series is really meant to be Smash Bros.-centric.
