I think it will work best for you if you bring it upstream to https://github.com/elogind/elogind/issues, they are better equipped to help you. package maintainers are usually not the best substitute for upstream developers when something like a 'business logic' goes wrong, like on your report, does not looks like anything Gentoo specific goes wrong here.
