I don’t think there’s anything preventing someone from forking it into an out-of-tree patchset or alternative module, if they’re enthusiastic about the feature. But I’m pretty sure that searching for someone to rewrite a non-core function that most people don’t care about is way outside what Linus and the various core maintainers want to do with their time. Normally open source is about people scratching their own itches.
From a health-of-the-Linux-ecosystem point of view, Gentoo developers seem more prone than those working for other distros to actually pay attention to things like broken build systems or test suites, and file bugs against them. This is especially the case for exotic arches that the developers of some software claim to support but don’t themselves build for (but it affects amd64 too).
