No. Jonathan was co-maintaining KDE neon, which now has one developer left and is about to be joined by KDE Linux, another take on a Plasma-based distro. He also handled release manager duties, which have been transferred and running smoothly for a few months now.
He may have contributed in other ways that I'm not aware of, but overall KDE is in a very good spot with many more developers working on stuff.
