That's a shame, it's the way the industry is headed.

Anything can change, but I rarely change file locations without any good 
reason.
In this case, no daemon should really write to the system config folder 
where is was previously.

If it does ever change, it will only be for a major release (ie dhcpcd-8 
... probably not minors like dhcpcd-8.1) and it will be in the change 
entry I post to the list here.
