I was the one who initially proposed to use \RequirePackage instead of
\usepackage, since I had got the impression that the latter wouldn't work
if the package was already loaded earlier, but I stay corrected and will
submit a corresponding patch to CVS.

I'm not sure what you mean here. One issue was if we should use
\usepackage{graphics} or \usepackage{graphicx}, but from Sect. 4.7
of `texdoc grfguide`, I learnt that we should use the graphics package.
