Export all helpers in root

[csnover]

This just seems like a thing to me where it should be all or nothing, because I think splitting the difference gives a false impression that there are fewer helpers than there truly are. So here is the ‘all’ approach, for the sake of having a discussion. Considering that these helpers are all exclusively for the sake of reading, I do myself wonder whether or not the ‘none’ approach is better and/or that they should be moved into a read module or something.
