No one is "proud" of it.

Any language that has been around for 40+ years and 5 major revisions is 
going to have a few ideas that were not worth the effort. Dynamic 
accessibility checks seem to be in that category. (So far as is known, no 
compiler correctly implements them for Ada 2005/2012, and that hasn't 
exactly led to an outcry.)
