Can I propose that we leave the old behaviour in place, I think I honestly prefer it and it makes more sense. If I run the config command and tell it to set a value, it should get set to whatever I specify. The default rhsm.conf has four empty properties by default (proxy settings). With this change, if we were to modify one, we can't unset it unless we take it out of the config entirely, whereas previously we could. Once it's gone from the config file it starts getting pretty hard to remember just what properties are supported and which aren't. I can't see any gain here, we may very well have config properties we want to set as empty, why block it from CLI?
Spoke with zeus and jsefler who are agreed the old behaviour is probably preferable, as we do make use of empty properties quite regularly.
