PFA systems and procedures are now quite slick. I got my permit sorted almost by return of post a few months ago and a modification dealt with in a few weeks. The problem for the engineering team is too many modification requests are either insufficiently documented, or badly thought out. As a result there are always a small number of people heckling from the sidelines, which is a shame as the vast majority of the owners of the 2200 aircraft flying and 2000 under construction seem to be very happy.
If we ever get an experimental category, the PFA will cease to be liable and the system will improve, but it is EASA not the PFA who will have to be convinced to do this.
