Sorry, I don't follow. The 2011-03-20 change put a copy of 'configure' into autogen/configure, and autogen/copy_autogen creates an up-to-date copy of 'configure' from 'autogen/configure'. So I don't see why the problematic dependencies are needed after autogen/copy_autogen is run. It's true that 'configure' is not under revision control, but the problematic dependencies aren't needed to keep it 'configure' up to date if one uses copy_autogen. Or perhaps what you're saying is that the dependences are needed if one wants to edit 'configure.in', then do a 'make' and then run autogen/update_autogen? That's true -- but only maintainers do that, so it's OK to require maintainer-mode for that, and a maintainer should invoke the pre-2011-03-20-style 'configure --enable-maintainer-mode' to enable those dependencies before doing something heavy-duty like that.
