development direction of OpenCV elements

[hubbup]

There are OpenCV elements in the bad plugin.
I want to know the development direction of the OpenCV elements.

1. Should an element contain only one OpenCV function?
     (I think cvdilate and cverode can be merged and
                 cvsobel and cvlaplace can be merged)
2. Do we have any plan to support OpenCV 2.x or OpenCv 3.x?
     (OpenCV 2.X recommends to use "Mat" format rather than "Iplimage".)

Thank You!
Best regards,
hubbup.
