I think the main TLDR here [1]: > For example, I tried recompressing the latest version of the typescript package. GNU tar was able to completely compress the archive in about 1.2 seconds on my machine. Zopfli, with just 1 iteration, took 2.5 minutes.

Or is backwards compatibility strictly necessary? I understand that GZIP is still a good compressor, so those others may not produce meaningful gains. But, as the author suggests, even small gains can produce huge results in bandwidth reduction.
