 Stem looks for it, and
 [https://gitweb.torproject.org/stem.git/blob/HEAD:/stem/descriptor/networkstatus.py#l1491
 raises an error if the "published" line isn't found]. Which means that
 BridgeDB (in the development branch which uses Stem)
 [https://gitweb.torproject.org/user/isis/bridgedb.git/blob/refs/heads/fix/9380-stem_r3:/lib/bridgedb/parse/descriptors.py#l39
 fakes a "published" line]. (This would remove the need for BridgeDB to do
 that, in the future.)

 I ''think'' that the `metrics-db` code should be okay, because
 [https://gitweb.torproject.org/metrics-
 db.git/blob/HEAD:/src/org/torproject/ernie/db/bridgedescs/SanitizedBridgesWriter.java#l517
 it appears to have a catch] for when it finds lines which do not begin
 with `"r"`, `"w"`, `"p"`, `"a"`, or `"s"`. Otherwise, in order to not
 trigger that error, it could easily be taught about the new bridge-
 networkstatus "published" lines [https://gitweb.torproject.org/metrics-
 db.git/blob/HEAD:/src/org/torproject/ernie/db/bridgedescs/SanitizedBridgesWriter.java#l448
 where it handles the other networkstatus descriptor headers].

 Karsten, any thoughts on the above?
