If only a certain Redmond, Washington company that "loves linux" would be willing to spare a developer for this popular filesystem...
Apparently, the NTFS source code is so insanely complicated that maintenance is a problem even within Microsoft. Due to the usual recursive kludgefest of backward compatibility requirements, a greenfield cross-platform replacement would also be more trouble than it's worth.
I often forget how nice APFS is until I have to use NTFS.
