But is a fundamental of zfs:

       snapshot

           A read-only version of a file  system  or  volume  at  a
           given  point in time. It is specified as filesys...@name
           or vol...@name.
Erik Trimble's assessment that it would be difficult to implement is much
more valuable.  Because the above quote is trivial to change.

It's a lot more than that, to quote Eric, it is "a fundamental design decision made when ZFS was started". Snapshots have always been read-only and have defined that way from day one in all publications describing ZFS.

Changing words my be easy, but this more than changing words.
