Yes, but they are not going to be updating to a newer version of
systemd, right?

And they are going to be "supporting" that for 20+ years.  If they want
to do something crazy like this, make them handle supporting code that
is older than 6+ years to start with.  That's not the community's issue,
that's the companies that demand such crazy requirement's issue.

4.9 is fine, and is supported by kernel.org until next year as seen
here:

I wrote "4.9" above, not "4.19" :)
