I did mean 'interface' :-) . I was just trying to say that the launcher (/desktop) wouldn't have a hardcoded default for every interface it has to handle.

Given the confusion with the equivalent case in mime-apps, I might add a sentence like: "However, whatever we do should give a consistent result, e.g. it should not depend on the order of an unsorted list of files from a directory." I'm not sure about the last sentence you've now added: "A similar algorithm, apart from stopping at the first success, can be used to list all available implementations of the intent." I don't think it can, because, there's no reason to think that a given implementation is listed in any intentapps.list file. As things stand, to find all implementations, you would have to scan all desktop files. It would be possible to build a cache like mimeinfo.cache, but that's a separate concern from selecting the preferred application.
