   Is there any progress? I really like the `static_shape` part. Currently, the symbol has no `shape` attribute which makes it hard to use some ops in HybridBlock, for example
   
   ```python
   def hybrid_forward(self, F, feat):
       _B, C, H, W = feat.shape
       x = F.linspace(-1, 1, H)
   ```
   even if I know the C, H, W will never change and I will never access the batch size B. I only need the shape once and the shape should be cached. This RFC may fix it.
