Use imagemin-zopfli for PNGs?

[nisbet-hubbard]

sharp uses pngquant under the hood. Among recent tools, zopflipng seems to give the best lossless compression rate.

Would it make sense for this project to transition to imagemin-zopfli at some point?

It’s slower, but I guess that shouldn’t be an obstacle if the optimisation is meant to be one-off.

Thanks @nisbet-hubbard! Generally interested in best results, too, but it seems that the whole imagemin-* family (with the exception of independent packages like imagemin-guard) are unmaintained. imagemin-zopfli is at 3 years now (for their workflows), which makes me wonder if it would be an exception.

If there’s a signal that this or other imagemin-* packages are being maintained again, I’d have a look, but if not, I’d prioritize future improvements and likely better security with maintained packages (where possible).
