I'm not sure I understand the suggestion to mark it as tainted, what
exactly is "tainted" about using deprecated stuff?
I think systemd's builtin deprecation policies are probably sufficient
for now, especially as nothing actually breaks for now.
In this case I would not use a news post, but I might consider a
post_upgrade function in an install script for netctl itself which runs
once for the upgrade from 1.17 to (unreleased) 1.18, warning users to
refresh their profiles. News posts are usually for things which require
manual intervention *before* updating.
And as long as 1.18 isn't released yet, I guess it makes no sense at all
to warn people about something they cannot do yet. :D
