Mia, wouldn't this actually make things worse?

Or am I missing something basic?

Now, if I come across a CC BY-SA 2.5 work, I can hapilly use it under the
terms of CC BY-SA 3.0. (IIRC and upgrades exist in 2.5) If we make this
change, when I encounter a CC BY-SA 3.0 work, will I have to track down which
parts have come from some other compatible license and if they are still
compatible before I use the work in a BY-SA 3.5 license?

Is this an off the wall concern due to lack of understanding?
