JFTR:

I just checked if reverting a few patches would help us in an easy
way, but the changes seem to be too invasive.

Sadrul bumped the msg struct version deliberately in these commits:

>From the commit message of the last one:

    A small change in the messaging system is necessary, thus bumping
    the message version, for the first time since it has been
    introduced, it seems. But I don't think it's going to break
    anything.

Well, I guess we have a different opinion WRT to the breakage caused
by this commit. ;-)

For the discussion, the commit message refers to
https://savannah.gnu.org/bugs/?24029
