Well, Domain acts as a factory for the transaction, based on its own  
configuration. In 3.1 we'll have a DI container that is a factory of  
everything. Although there will be 1 DI container per Domain. So it is  
not going to change in 3.1.

Yeah I also don't like a single delegate model (and may change that in  
3.1). Nothing would prevent you from aggregating multiple delegates  
within one delegate on your own, but since we are talking about  
possible improvements, this is a valid point.
