It's pretty plausible that this commit is simply incompatible with the previous version of sshd, therefore it could not reexec: https://github.com/openssh/openssh-portable/commit/c2bd7f74b0e0f3a3ee9d19ac5...
So this is "expected" behavior.
That seems likely indeed. What troubles me is that upstream has never broken live SSH daemons in such a way before, maybe it was just pure luck, but I had assumed this was a conscious design choice on their part.
It could be this one was too difficult to handle since it changed the way marshaling the sshd_config worked? I suppose you'd need to double-check with them. In the meantime, it is definitely not just us: https://bugs.gentoo.org/709748 -- Eli Schwartz Bug Wrangler and Trusted User
