Bundling vs Mapping

[Shawn Steele (???)]

There's lots of discussion of bundling of related names instead of mapping.  I'm curious how that behaves when round tripping?

Presumably a registrant would like a specific name.  Related names are also interesting, hence bundling, however there is probably one preferred specific name.  How does the client device get from some input variant to the preferred name in the UI (eg: browser address bar)?

Bundling also has some limitations.  Bundling (or not) Eszett with ss may be interesting and helpful, however that won't scale to casing.  Currently DNS is expected to be case insensitive, and it isn't really practical to register all the variants of some IDN form of mYdOmAiN.com.  So there's still a question of mapping, clients are still going to have to do at least some mapping.
