If a package places a sysctl file in /etc/sysctl.d/ then you can
override it with /etc/sysctl.conf, hence everything is as it should, no?
This whole logic is designed so that the admin's configuration always
takes precedence over vendor configuration. Which is the right thing to
do.

That said, note that it's probably a good idea if packages stick their
sysctl files in /usr/lib/sysctl.d instead, so that that users can use
/etc/sysctl.d/ to override that. /etc/sysctl.conf is read mostly for
compatibility reasons only.
