I think this is the heart of the issue. The ILDA standard evolved into format 4 and 5, which *is* different from the erlier versions. I see James' point on that score.
However, Keeperx nailed it. The format has evolved. The decision was made long ago. Regardless of the technical merits (or lack thereof) of that decision, it's done.
Also, it was designed by a committee, which means it's a compromise. And we all know that a good compromise leaves everyone angry!But seriously, at this point it is what it is, and the laser software industry has had to adapt to it.
Personally, I don't have a problem with it. I can still create ILDA artwork, and I've yet to run across a program that won't work with the files I have. (And that includes the alphalite software, the X-29/Full auto software, the Anarchy editor, Mamba Black, Spaghetti, LaserBoy, and Pangolin.)
