I suppose it is possible, however sshd(8) is linked against
/usr/lib/private/libssh.so, not /usr/lib/libssh.so after the userland
bits are installed.

Generally, no.  freebsd-update does not really care what version you are
running when upgrading, and would install any updates to the latest
point anyway.

In think it already does.  But in this case, it would not matter because
the ssh_explicit_bzero is a symbol in a userland shared library, not
part of the kernel.

Yes, this is why I tested the upgrade path from 9.2-RELEASE through
9.3-RC1 then to 9.3-RC3, in case there was an incompatibility somewhere
earlier.
