I am not sure about this. Wouldn't it be some kind of abstraction leak? |

IMHO that ship has sailed, this info is already sent as part of the execute
request from front end to here, and is already used by other kernels. The
goal is also to help having a mapping from execution/limiting to original
cell.
I agree that kernel should be able to work without, but I also don’t see
any reason to prevent it.

I should probably add some test that subclasses/methods that both do and do not support gettign cell_id behave properly. I'll try to do that at least. |

Is seem that few kernel want to make use of cell id for various reasons. One way to get the cell_id in the executing context is to make use of init_metadata but it is marked for removal. for example in [there](https://github.com/robots-from-jupyter/robotkernel/blob/19b28267406d1f8555ce73b96e7efb8af8417266/src/robotkernel/kernel.py#L196-L205) Another is to start passing cell_id down. This is technically a change of API as our consumer may not support more parameters so we take a peak at the signature, and pass cell_id only if it is : - an explicit parameter, - the function/method takes varkwargs. We could also start to refactor to pass a metadata object with multiple fields if this is the preferred route. One questions is whether and how we want to deprecated not receiving cell_id as a parameter. Related to ipython/ipython#13579 and subsequent PR on IPython side to support cell_id in progress.

The remaining failure has been fixed downstream in ipyparallel. |
