I will try to find the IRC log about this discussion to know the reasons (it should be in my home computer). I know it was in "[task #6969] Review usage of conn->err in netconn layer" if it can help...

I think before that, we did not have non-fatal errors at all (meaning there were checkes for conn->err == ERR_OK at some places) and as I did not convince him, we added the 'fatal' check as a consensus. However, I'm still not totally satisfied with this solution...
