No, we have a pretty good idea of ntfs now. But it is a complicated fs and when writing you need to take care of a lot of things simultaneously or you corrupt the volume. ntfs is organized as a transactional, relational database , hence there is a lot of book keeping involved in modifyin any structure. Even without supporting the journal (we will not support it at least initially...) almost all data is duplicated in various places and if you forget to update something somewhere when updating it elsewhere you basically make salad of the metadata and the probability is quite high that you end up killing the data on the volume either in part or completely... Finally I am busy with my PhD and I have two part time jobs as well so I don't have much time to develop ntfs... As always with free software development, it goes slowly...
