I remember when this was introduced about 15 years ago, everybody pulled their hair and said this was so difficult, so much paper, so much process. It was seen as very burdensome. However, after it was implemented and people started to work with it, they realized they could do it and it was useful. Now it's not an issue any longer.
Of course when it's introduced it's always difficult and burdensome, but it has been running for about 14 or 15 years now and it's a non-issue.
