So is it easily possible to docs of llvm ports to be separate ports?
Doing so and mixing into home brew builds (including pkgs by poiudriere
and so on) shoule be 100% safe, as docs should be data-only.

What can cause problems by mixing up home-brew binaries and official
pkgs are pkgs including executable (exclude extract/patch-only pure text
scripts) and/or libraries.
