This implies that OpenSSL 1.0.2 in stretch has to support EMS.
Reality is that a significant part of the archive will likely
use 1.0.2 in stretch, and planning should not be based on the
unlikely case that everything compiles and works smoothly with 1.1.0
The soft freeze is only 2 months away, and therefore a complete
transition to 1.1.0 in stretch would imply that libssl1.0.2 must be
removed from testing in November if it should not delay the whole
release - I'd expect there will be plenty of runtime bugs in both
OpenSSL itself and the 1.1.0 support of various users that will
require debugging and fixing, and runtime testing of everything
has to start ASAP.
If everything that is important in 1.1.0 should be used by all
users of OpenSSL in stretch, then the best solution for stretch
is to ship only 1.0.2 and add all desired features there.
1.0.2 is also LTS, and has upstream security support for an additional
16 months after upstream support for 1.1.0 has ended.
I am aware that this is not a nice solution, but since there does not
seem to be a realistic 1.1.0-only solution without impact on the release
schedule it might be the best among the available options.
