that would be awesome if it was.

I was testing the upgrade in an almost vanilla jessie VM that I had
created with vagrant. I installed "mysql-server", and then proceeded
with the install.
I didn't install "default-mysql-server" before the upgrade since I
wasn't tracking jessie-backports.

I was following this procedure (sorry it's a weird mixture of english
and french but you can probably make out most of it by looking at what
commands are there):

https://wiki.koumbit.net/StretchUpgrade

it's somewhat based on minimal downtime procedure here with added
convoluted steps to keep from upgrading the puppet client since our
master is not yet upgraded:

http://www.debian.org/releases/stretch/amd64/release-notes/ch-upgrading.en.html#services-downtime

so after both the upgrade and dist-upgrade, I tried connecting with the
client and the server wasn't there. I unfortunately lost the package
list that I sent in my first failed attempt at opening this bug. but I
could reproduce and give you more info if you'd like.

from what I can remember, only the mysql-server-5.5 package was marked
as uninstalled.
