Is it possible for even more time-lines exist? (Theory thread)

Spoilers for those that haven't even touched Skyward Sword yet.

Do you guys think that all the time travel play in SS would cause any more issues or additions with the current timeline? I just recently saw the "official" timeline released online. I personally don't like it. I wasn't too much of a fan of the split timeline theory from the get-go, now three seems to be a bit much. Sooooo... with all the time traveling in SS, do you think that it could be a cause for even more time-lines to exist?

That's my question.

Edit: Formatting and messing up the title.
