The systemd guidelines in https://fedoraproject.org/wiki/Packaging:Systemd#Support_for_.2Fetc.2Fsysconfig_files seem to strongly imply but do not state outright that files to be loaded by EnvironmentFile should reside under /etc/sysconfig.

While looking at a prospective systemd conversion today, the maintainer had used /etc/%{name}/%{name}.params and I can't figure out if that's actually against the guidelines. This file does appear to be new with the systemd conversion, which I guess runs afoul of the suggestion not to add any new sysconfig files, except of course that it's not under /etc/sysconfig so there's room for argument.
