Thanks for the PR @neoremind.
At the moment, the community is busy working on the 1.5 release which means
that PRs for 1.5 fixes have priority right now. Also a large contribution such
as this one takes a lot of time to review. Unfortunately, I won't be able to
review the PR in the near future. Best, Fabian---
