The dependency remains in the code even if it's off by default.  I think
Stefan's objection is not to the default or to the licensing but to the
code complexity and growth.  In other words, the policy is not to scorch
the earth but to wait for the spring FFI cleanup :)

But speaking of licensing, what's the rationale for depending on
libcrypto (Apache licensed AFAICT) when, as we've mentioned here, GnuTLS
(through libnettle+libhogweed) offers very similar facilities from a GNU
project?  I'm not against libcrypto at all, to be clear, but I think you
should have an answer to the licensing question because project
decisions (notably the use of Bazaar) have often considered it.
