What's probably worth saying is that (at least for Apache), you can enable compression only for certain file types, such as static text files (HTML/CSS/JS) but not dynamic files (thinking of classical CGI scripting -- PHP/Python/Ruby). It should be possible to seperate this also for modern-world fcgi services. How does HTTP2 and HTTP3 perform in this question? I always percieved deflate/gzip compression as something preferable. I never realized the CRIME attack before.
