Hi Stéphane thanks for the proposal and the PR.

But are those options usefull in real life? (I may be biased as a Linux user).

I see this gzip CLI usefull to decompress a gzip file on platforms not having a gzip program installed, but I don't think it's usefull to compress. (Yet I'm OK with the current status-quo: If we allow to decompress, let's allow to compress, for consistency).

But why drifting from "let's allow to compress just for consistency" to "let's replace the gzip command"?

I mean, except is it's usefull in some cases that I don't see.

Also so does it mean we'll have to add the 16 other gzip options at the end?
