Yeah, we could, and it could presumably even be a fully compatible
dot-release with no change to the on-disk representation. That
representation and consequently the decompression algorithm are safe
enough, it's the details of the compressor's search for matching
patterns that are a patent minefield.
However, changing the code after-the-fact might not be enough to keep us
from being sued :-(. I'd rather use something that's pretty well
established as being in the clear...
