I am part of the Fedora Minimization team. I am dealing specifically with build dependency minimization. I am working on minimizing the build dependencies of nodejs libraries. This has two benefits. For the packager, it allows more flexibility. Currently, the nodejs libraries are so intertwined, it is taking a lot of effort to change the version of any specific nodejs library. For downstream, such as RHEL and EPEL, it allows those package maintainers to use the Fedora packages without having to pull in hundreds of nodejs library dependencies. rubygem-uglifier is currently only using uglify-js for building. uglify-js in turn pulls in over 200 nodejs libraries to be built and installed. If you could remove the build dependency on uglify-js from rubygem-uglifier, it would help me with my minimization efforts.
