I don't see any point for GetAliasFlags() of interface Telepathy.Connection.Interface.Aliasing to be a method instead of a property.
The number of round trips is the same, so this is not a high priority. If Aliasing gains a second property, we should opportunistically add a property form of GetAliasFlags too; however, I think fixing Bug #14540 would be a better fate for the Aliasing interface.
Won't fix. Instead, Aliasing should be replaced by nicknames on a Nicknames interface (Bug #14540) and "petnames" on a Roster interface or sidecar (Bug #21787).
