Well, Martin promised to reimplement it better later if there is demand for it, and it seems there is. So I suppose it's going away only to be replaced by something better.
There was a flamewar about this some time ago - whether the kernel should or should not parse the taskfile access to prevent possibly dangerous commands sent to the drive - if this is to be used for validation, then all commands need to be allowed, which also will enable to thin the code considerably.
