Re: EPP Implementation Test Matrix

Some registrars in their clients implementations don't rely on 
idempotency in EPP protocol and I can understand that the feature does 
not help them in any way. However there is a large group of registrars 
who explicitly or implicitly depend on the feature. Without idempotency 
enforced on the server side the ratio of registrars complains obout 
transform commands submitted "by mistake" would increase significantly. 
That would eventually lead to higher client implementation and 
maintenance cost. I would certainly not recommend removing idempotency 
requirement from EPP protocol. The feature IMO brings overall more value 
to EPP client than servers implementers and operators.
