Action statements affect the operational > state of the server. This wishy-washy language is the tricky bit: i) Actions are allowed to have any operational impact on the device (just as RPCs are), their behavior is not constrained in any way. ii) However, as far as I can see, it doesn't make sense for an action to directly affect the contents of any configuration datastore, that should be done via a purpose built rpc (like edit-config). My text was aimed to allow (i) but not encourage (ii) ... If your text is sufficient for this then it is fine with me - I agree that it is simpler, and simpler is preferable.
