------------------------------+-----------------
 Please add {{{ClientTransportPlugin}}} configuration to {{{/usr/share/tor
 /tor-service-defaults-torrc}}} by default. What I mean by that...

 {{{tor-browser/Browser/TorBrowser/Data/Tor/torrc-defaults}}} contains:

 {{{
 ## fteproxy configuration
 ClientTransportPlugin fte exec
 ./TorBrowser/Tor/PluggableTransports/fteproxy.bin --managed

 ## obfs4proxy configuration
 ClientTransportPlugin obfs2,obfs3,obfs4,scramblesuit exec
 ./TorBrowser/Tor/PluggableTransports/obfs4proxy

 ## meek configuration
 ClientTransportPlugin meek exec ./TorBrowser/Tor/PluggableTransports/meek-
 client-torbrowser -- ./TorBrowser/Tor/PluggableTransports/meek-client

 ## snowflake configuration
 ClientTransportPlugin snowflake exec ./TorBrowser/Tor/PluggableTransports
 /snowflake-client -url https://snowflake-reg.appspot.com/ -front
 www.google.com -ice stun:stun.l.google.com:19302
 }}}


 For {{{/usr/share/tor/tor-service-defaults-torrc}}} I suggest to add:


 {{{
 ## fteproxy configuration
 ClientTransportPlugin fte exec /usr/bin/fteproxy --managed

 ## obfs4proxy configuration
 ClientTransportPlugin obfs2,obfs3,obfs4,scramblesuit exec
 /usr/bin/obfs4proxy
 }}}

 (Left out meek and snowflake, because these are not yet in
 packages.debian.org. #13160 #19409)

 Why?

 * Improves usability. One step of configuration less. Fewer mistakes can
 be made. The user has no longer to add the {{{ClientTransportPlugin}}}
 line.
 * Using the canonical recommendation.
 * To be on par with Tor Browser.
 * {{{ClientTransportPlugin}}} does not have any effect as long as not
 adding a {{{Bridge}}} line.
 * {{{ClientTransportPlugin}}} lines do not change often.
 * {{{ClientTransportPlugin}}} can still be overwritten in
 {{{/etc/tor/torrc}}} by the user.
