And my point is that the feature/bug is there solely for backwards compatibility with g77. A POLA issue back when gfortran first replaced g77 in GCC. Just last week in c.l.f there was a long thread from someone who could not use gfortran to build his legacy code, because gfortran does not support a number of g77's old -fugly-* options. In hindsight, I now regret contributing a number of patches to implement g77 compatibility and common vendor extensions. In fact, I think the default should be -std=f95+f2003+f2008. If the feature isn't in one of the standards, an error should be issued without an explicit option to permit the feature. Unfortrunately, the horse left the barn years ago.
