I can't comment on your first two issues. But for the third one, FWIW, keeping the original coordinates would produce a file that is no longer correct according to the definition of the MAF format, which can be found here:

So to do that I need to take the length of chromosome and subtract the start position from it, then subtract length and only then I get the same coordinate as in my set of intervals.

This is the reason why the MAF format carries the chromosome length on every line.

Someone could make a tool that does it the way you suggest. Hopefully they wouldn't call the result MAF.
