Hi,
I know I know.. you said tess shaders were coming not soon(tm).. :-)
anyway I searched that Wine added support for tess shaders in version 2.9 and mentioned as bug fixed:
https://bugs.winehq.org/show_bug.cgi?id=41184
(DX11 Tesselation tutorial doesn't work correctly)
I mention because this is a very minimal D3D11 test app using tess shaders complete with executable and source code too:

Hope it can help with your eventual efforts adding tess shader support..

Works as of 88c4e363e5f079bb54de44c92b6867073812707f.

Note that this does not mean that tessellation support is complete, more complex apps like Heaven or Witcher 3 are still broken, but we're getting there.
