The feature introduces a substantial performance penalty for a dubious
and poorly understood privacy gain.  If I were to write an algorithm to
detect obfs4, I wouldn't bother dealing with its flow properties; there
are easier ways to identify the protocol.  In hindsight, it was probably
a mistake to expose the iat option to users and bridge operators.
