Weird, I have around a dozen RPi 2/3 class devices on both wired and
wireless network with a dual stack IPv4/IPv6 and I don't see that at
all (and never have).
Nor have I had other reports.

That will turn the wifi off but if you're not connected to a wireless
network it won't have any effect.
To disable IPv6 privacy on the wired interface you can do:
nmcli connection modify eth0 ipv6.ip6-privacy 0
There's a couple of blog posts with some good details:

This problem showed back up this morning. This morning the kernel was
updated to 4.20.13-200 and the machine was rebooted.

Is it just the unstable addressing that's weird, or something else?
This IP address problem, Bash's reverse search not working, missing
utilities, ...
