We're very aware that using these internal functions ties us to a specific version of R, and that they may change at any point in the future and break our code. That's an acceptable trade-off - using these internal functions gives us capabilities that makes fixing the code in the future worthwhile. A minimal change to R that would satisfy our needs (and I suspect Daniel's) would be to move makeNamespace into the base package (i.e. up out of the function it is currently contained in), and to create R wrapper functions for registerNamespace and unregisterNamespace. They wouldn't even need to be exported - we know what we're doing is dangerous. If that solution isn't acceptable, we'd also be very happy to work with any R-core member to help develop a public facing API for namespace manipulation, including providing tests for common use cases. Please let us know what we can do to help!
