+Can you think of any use case for the uuid with the other count outputs?\r
+It feels pretty artificial to me.\r
+\r
+Another option is to make a "notmuch metadata" command. I'm not really\r
+sure about the syntax, but perhaps a uuid option makes more sense\r
+there, so e.g.\r
+\r
+       notmuch metadata --with-uuid lastmod\r
+\r
+I'm pretty convinced that we need report uuid and lastmod together (at\r
+least optionally). I'm less sure we need a full get/set interface for\r
+metadata, since people with that use case could use xapian-metadata.\r
