The use case here is that we have data sets of sensitive data that we are contractually obligated to delete with no backups at a certain point in time. The datasets are stored on a ZFS filesystem (on a truenas from IxSystems as it happens). The snapshots are kept for 15 days, so at the moment we have to rm the files 15 days before the deadline to be compliant. Is there a way to delete a specific file from the live filesystem as well as all the snapshots? I did find a post to this list from 2014: https://lists.freebsd.org/pipermail/freebsd-fs/2014-October/020307.html but I don't think it is relevant, and in any case it does not appear that the feature that post describes was implemented.
