I don't need it so I don't object.  But if anyone objects,
you could write a compatibility module that can be called
to use the new interface to change in a compatible variant
of the old wrappers, which would then provide the old
hooks/facilities when needed while staying out of the way
(not even being linked into static programs) for the rest
of us.

I guess this is because that interface is not a part of a
commercial grade full featured SSL/TLS and general purpose
crypto library, it is just a means to do quality assurance
on said library.


Enjoy and Merry Christmas
