As I understand it, the write support is rather limited, and debugging and fixing read support is generally a lot easier for a variety of reasons. There's also a lot less risk to data. :-) I think it's reasonable to surmise that, given our rather limited write support currently, the kernel ntfs code is used for data migration and limited sharing to FreeBSD in various forms, but that msdofs remains the general data transport of choice...
