I would like to be able to remove a registered ContactType.  
I’ve added one using  
`gatewayContext.getUserSourceManager().registerContactType(newContactType);`  
and tried to remove one using  
`gatewayContext.getUserSourceManager().getRegisteredContactTypes().remove(oldContactType);`  
It doesn’t seem to get removed from the system (I’m guessing getRegisteredContactTypes() is creating a new Set).  
Is there a way to do this?

It doesn’t look like there’s a way to do this in the current API, no. What’s the use case? Each gateway startup the contact type would have to be explicitly registered to appear to end-users, so if you remove the module your new contact types will be (visibly) cleared up on the next restart.

That said, if you _really_ need this functionality, it should be possible with some reflection, though that is absolutely going to break in 8.0+. The (private) field on the UserSourceManagerImpl class is just `contactTypes`. I’ll leave the rest an exercise for the reader.

My module adds a new notification profile type, and for each instance created of that type on the gateway I wanted to add a new ContactType. So, when sending a notification with a given profile, only contacts relating to that profile would be notified.

I don’t think I need the functionality enough to take the reflection route, so might have to rethink my approach.
