Opt-out of Group Messaging on iPhone

Does anyone know if Apple will create a button to completely opt out of Group Messaging? I would be nice to just turn off Group Messaging and totally block any kind of group with the a custom "except for" option. You shouldn't have to be subjected to a group without your permission. It's invasion of privacy. I'm already aware of the "delete and block this conversation." However, we should have the option to not be invited if we wish.

Anyone else feel this way? @Apple (www.apple.com) (question) please make this available.
