   See https://discuss.tvm.ai/t/discuss-adding-a-pytorch-frontend/5026 for a 
RFC on adding the PyTorch frontend.
   
   Yes, discussion with respect to ONNX is common when adding a new frontend, 
and the PyTorch RFC above gave some reasons adding the PyTorch frontend could 
be justified. You want to have similar story for Chainer, more specific than 
"Chainer users would benefit" or  "attracting more users".
   
   Note that unlike other frameworks, Chainer doesn't even have a well defined 
IR we can translate from. You need to start by developing some kind of tracing 
mechanism.

   You should first send a RFC on why you want to add this frontend. I don't 
think it is a good idea for the following reasons:
   
   * Chainer is now in maintenance mode
   * We already have ONNX and PyTorch frontend. Existing Chainer users are 
being encouraged to switch to PyTorch, so they can use either frontend
   * Additional frontend brings more development and maintenance burden 
(including reviews), and makes CI even slower
