This is a known problem, see http://darktable.org/redmine/issues/9974 I made a proof of concept in <http://pastebin.com/5BRvG8W9>. This code already uses Lensfun's structure so that I can incorporate this in LF. It even allows for a UI slider for finetuning. LF would then be also able to rotate, so that all coordinates-bending operations could be computed in one pass without leaving the floating point realm. All of this is easy to code. But the necessary changes in DT (in particular, moving a lot from "clipping" to "lens") is a lot of work that scared everybody off. Alternatively, only the clipping module in DT could be changed, which is a lot easier probably.
