I read over the short account. The telling statement:

"Due to the amount of CPU time required — 2 to 3 orders of magnitude more than zlib at maximum
quality — Zopfli is best suited for applications where data is compressed once and sent
over a network many times, for example, static content for the web."

So, I'd think that using this new algorithm for installations sets makes sense. For all other
uses, I'd agree with you, it does not seem useful for us.
