(Currently on holiday) Unbounded intervals have always been out of scope for Joda-Time, partly because they mess with your expectations when using the API (everybody typically needs to constantly check for the edge cases).
I wouldn´t plan on adding them or accepting patches. I´d recommend your own domain objects to handle these cases. Or if you want to open source, set up your own project and I´ll link to it from Joda-Time.
