It is doing that (see today's version of the NEWS), but the problem is that it may choose the wrong one. If your package requires initialization then yourpkg::somefun only works if the initialization happens in .onLoad. But some packages only work if the initialization happens when the package is attached. It's better for the author to make the choice than for R to do it automatically.
