Anvart, it is not feasible to do so, and from a technical standpoint there's no reason why this should be done nor is there a benefit to gain.
Bottom line is there is no point in making sure the import function reorders the uv's exactly like the original. If the function is procedurally correct (aka. if the model renders correctly), then I don't care if the ordering is different (and in fact in some cases better!). The result is what matters.
And another thing. I've done tests where I didn't optimize the export either (yes, the export is optimized as well). The result? Some 3D studio's strip all the unused data and reorder the tables as well. So I don't do anything crazy, see?
I know what I have done, and why I have done it. Time for you to trust me.
(this doesn't mean there could be bugs in the whole implementation, but that's a different thing)
