Unfortunately that's not the case. I'm using Gnome, upower is installed, but there's no org.freedesktop.PowerManagement service. This looks like the page for the freedesktop API:

https://www.freedesktop.org/wiki/Specifications/power-management-spec/

"This is no longer supported in gnome-power-manager. This spec is considered obsolete."

I've no idea why it's obsolete, but it does look like you'll need to keep supporting different interfaces for this.

Best wishes,
Thomas
