That's because it doesn't make sense. :)

Dumping that kind of data volume only really makes sense locally.  And
if you can't run it locally, scp the data files to a machine you can
run it on, and do it there.

(The local export tool, for those who don't know, is bin/sstable2json.
 That should have made CHANGES.txt, but didn't.  Oops.)

Also true.
