Review / merge PR #4297

Pull Request #4297 has been open for almost a year now, but I see zero activity from repo owners / maintainers.

Honest question: if this project is all but abandoned, perhaps it should be marked as so. Then hopefully somebody will take over and maintain an active fork. Or use [a bot](https://probot.github.io/apps/stale/) that will close / label stale issues, because 614 open issues (the oldest one dating back to Apr 14, 2015) sounds quite unmanageable to me.

It is not very motivating to go through the time and effort to contribute code to the public repository if nobody takes the time to review or respond. I'm sure everybody is busy (so am I), but a year...

Issues that could potentially be solved by merging #4297 are _at least_ the following issues: #4432, #4494, #4411, #4375, #3754, #1066, #4552, #4540, #4500
