Any plan to officially implement the deformable convolution in Keras?

[LeeJayHui]

Deformable convolution operation is interesting and effective, as introduced in https://arxiv.org/pdf/1703.06211.pdf. And the implementation of deform_conv by the author of that paper is in Pytorch.
I'm wondering if there exists any plan to officially support deformable convolution in Keras? Almost all of the Keras implementation of deform_conv on GitHub are confusing and inefficient. I tried to
implement it, but I failed.
So, plz add deform_conv to your plans of improving Keras. Thanks.
