Comment:

 I believe that a change to Tor's bridge line semantics is in order to fix
 this ticket. The bridge line is currently defined as:
 {{{
 Bridge [transport] IP:ORPort [fingerprint]
 }}}
 How about we change this to:
 {{{
 Bridge [transport] IP:ORPort|implicit [fingerprint]
 }}}
 If both `transport` and `implicit` is set, Tor won't pass anything to the
 PT. Here's an example for snowflake:
 {{{
 Bridge snowflake implicit 2B280B23E1107BB62ABFC40DDCC8824814F80A72
 }}}
 Alternatives to the keyword `implicit` are `auto` or `dynamic`.
