I rather not embark on writing and finishing code on something no one wants besides me.In my opinion, the marginal benefit of per-write(2) versions over snapshots (which can be per-transaction, ie. every ~5 seconds) does not outweigh the complexity of implementation and use/administration.
disclaimer: I have not used zfs snapshots a lot as I am still experimenting with zfs, but they appear to be similar to freebsd snapshots, with which I am familiar.
The user experience with snapshots, in terms of file versioning (#1, #2, maybe #3) is much worse than a true file versioning user experience. People are oriented to their files, not to snapshots. And I may not want versioning with all my files (object files etc) which you would get with the snapshots.
