Remove a feature module without losing the configuration that was defined by it. (eg: Features as one-off configuration scripts)

Sometimes you want to disable a feature module, but not lose the functionality or configuration that was defined by it.

I'd like to use Features to create one-off configuration scripts in order to move configurations from one site to another, but without creating a mess of features which do very little and would never work on their own anyhow. So, I'd like ot be able to delete the feature files after they are enabled and do their thing.

Can this be done? If not, please convert this to a feature request, as this seems like a pretty reasonable use case: using features as a global import/export method as well as a compartmental site building method.
