At this point, I'm not sure that a compromise would achieve anything without creating additional problems. The basis for lobbying to remove the quantitative limits is that they're arbitrary. The prudent person standard is more appropriate and in keeping with best practices globally. So to put in place restrictions relating to the investments would just be counter-productive. To put in place guidelines relating to the benefits, such as the inability to take contribution holidays and the inability to make changes to the benefits, is a separate issue.
