Comment (by mcs):

 Replying to [comment:10 arma]:
 > In theory you should be able to put all the ClientTransportPlugin lines
 in there by default, even when there are no bridges set, and Tor won't
 launch any of them until it has a bridge that needs them.

 FWIW, Tor Browser on desktop has used this approach ever since when we
 switched to Tor Launcher (i.e., for a long time now). The following gets
 appended to the `torrc-defaults` file which is always loaded by TB
 desktop's tor:
