power-profiles-daemon was moved into the UPower namespace,where it changed its bus, path & interface names from the originalnet.hadess.PowerProfiles to org.freedesktop.UPower.PowerProfiles.
These new names are advertised starting with v0.20 released inFebruary 2024. The old names are still supported at least in thecurrent v0.21, but we don't know for how long (or on all distros,given that OpenSuse already tried to remove it early on).
A February 2024 release seems long enough ago that we shouldn'trequire support for the old interface anymore. Rather than addinga second interface and introducing complexity, let's just makea clean switch to the new name while both are supported.
CC @ngompa in case you have opinions on this vs. https://github.com/redhat-performance/tuned/issues/683 which I just filed. Given that tuned wasn't supported so far, and its declared purpose is providing a compatibility layer for p-p-d for Fedora, I think the responsibility is on their end to be supported as a UPower replacement going forward.
