It's a good idea, but I've found it to be pragmatic to not worry much about 
error message quality during the initial implementation, just focus on getting 
the semantics right. (Doing great error messages often is a significant increase 
in complexity.) Having some experience with the kinds of mistakes people tend to 
make (and it isn't random) helps a lot to guide error message development.

Hence is it something for the future, and is premature to add in the DIP for the 
feature. Doing it later also would not require a DIP.

Good error messages are always a work in progress.
