 It will probably make life easier in the future if we add a version number
 to the JSON output from operations like {{{deep-stats}}}, {{{deep-
 manifest}}}, and {{{deep-check}}}.
 A related piece would be to tell developers that they should tolerate the
 presence or absence of each field.
 On the other hand, the only customers of the t=JSON are:[[br]]
  1) The Tahoe CLI[[br]]
  2) Tools written to use the webapi functions[[BR]]
 I'm ok with requiring that you use e.g. a 1.3.0 CLI with a 1.3.x backend
 instead of a 1.4.x backend, and developers have to play catchup all the
 time anyways. So I'm not sure how much energy I want to put into this.
