Well if someone publishes code under C-FSL he needs to be a (/one of
the) copyright holder(/s) in order to have the right to re-license under
C-FSL. If so then he is perfectly fine to do so. In this case it is
likely that the elder authors could publish under C-FSL without crypto
support and those who have added crypto support as well because they
have contributed a major part of the code (assumed that the previous
product was already C-FSL or open source).
