Apache has dynamic modules too, and they're generally better designed. In nginx they were added later and a module compiled against one version of nginx won't work against any other. With Apache you could download a mod_brotli binary module and use it with any (2.4) Apache build.

(I used to work on mod_pagespeed)

That's what I had hoped for, but I didn't come across any stand-alone builds of mod_brotli, only the one included with 2.4.
