Hooking a tangent onto this: I have no idea, based on the current
source code, which layers of complexity are necessary for which
reasons. Possibly as a side effect of this transformation, you might
consider adding some comments to the code? There are a few (citing
tracker issues such as #11647 and #27112), but they don't cover
everything.
