Contracts ?

Hi There

I have noticed that one cannot alter a contract, there is no alter contract syntax.

I understand the reason is because one can break applications by altering messages in contracts used to build apps.

However now it seems that everytime i create a new message type i have to create a new contract which in turn i have turn alter a service to use it. I cannot drop and re-create contracts because they are bound by services.

So basically what i am saying is that it is really a mission to add new messages types in a complex SB application (create new message+create new contract+alter service), is this just the way it is or what am i missing here ?

Thanx
