MarsSeed [1] filed a deletion request for opendds [2]: Unneeded, unused double library package from 2020. Bundles in an old version of the library called ace, so it states it provides and conflicts with that. But there's a newer version of ace as a separate package on AUR, and only that one has actual consumers. This one is not needed by any other pkg. Safe to delete.
