However, if I add more than one ThreadFactory, the last overwrites the previous, meaning I can only have one ThreadFactory.

OK, I think (hope) this is simple. The "add" operation for threadfactory 
=> * needs to registered as part of the subsystem's implementation of 
NewExtension.initialize(NewExtensionContext context).

The registration of all non-subsystem operations will be done statically 
as part of the server, DC or HC boot. For example, init() in
