I assume nothing just because the code for other protocols isn't using 
ft_mode.  However, for -incoming exec the parsing code as it is now 
would trigger if the executed file ended with "ft_mode".

So now I think it should be at the beginning of the scheme for forward 
compatibility with everything.  Is it possible to detect a migration 
scheme that does not support Kemari, and give an error in that case?
