There are plenty of decode-time knobs, even within a single ZIP parser. Here are just a few you could set while using libzip[1].

That’s not a lot of settings, and that’s libzib, which is not zlib.

		Differentials are oracular; you only need one bit. And I’m not claiming it’s in zlib, since zlib isn’t a ZIP library. TFA here is about ZIP differentials, not differentials in DEFLATE stream parsers.
