That's fair enough, maybe I could redo the PR where instead of putting the
Dockerfile in the repo,
an example definition that users can use for their own Dockerfiles if they
wish to build jextract
is provided in the documentation?

The problem I was hoping to solve is preventing users from needing to
manually install and
configure things like the right version of the LLVM toolchain for their OS,
etc

Would this be an acceptable compromise? Or is something like this still
better off in third-party land?
