 > I don't understand its purpose either

 It was added in, https://gitweb.torproject.org/pluggable-
 transports/snowflake.git/commit/?id=ac9d49b8727b953c12a76e3645fe71a9ec3aab75
 which doesn't provide much info.

 It might be related to, https://gitweb.torproject.org/pluggable-
 transports/snowflake.git/commit/?id=cf1b0a49f13f2550cad1b32ef4e4820b4c26bcf1
 where the client could be sitting around for several minutes waiting for
 the datachannel to close because the proxy disappeared.

 Or, a denial of service where the proxy keeps the connection open but just
 doesn't send any data down the channel.
