Yep, I noticed your name in the credits. Looks like a really interesting
file format.

Such is life.

On the proposal for adding LZMA2 into gzip I read a thread somewhere on that
topic. (I don't have the reference anymore) It argued that adding a new
compression format to the gzip would cause havoc. The reasoning was that
there were a lot of gunzip implementations out there that didn't check the
Compression Method byte in the gzip header and just blindly assume deflate.
If I remember correctly the thread was concerned with http proxy servers.
