FIX often standardize everyone's favorite custom fields after few years. The problem is that nobody is upgrading yet keep adding custom fields to their implementation, even worse sometimes back-porting tags from newer version but in incompatible ways (5.0 SP2 was released on 2011, but I've never worked with anything above 4.2 that was released 15 years ago.)
