That's cute and all, but it's fucking gzip. It doesn't have complex dependencies.

Pretty sure Linux could run a 30 year old gzip binary too. I've never needed to do that with gzip but I have definitely run binaries of a similar vintage without issue.

Windows backwards-compatibility fails miserably on non-trivial programs, you're generally pretty lucky if you can get something from the XP-era or older to work out of the box.
