Python host vs target C implementations

[sammyj85]

The host implementation appears to be only provided in Python, and the target implementation is provided in C.

It appears based on some comments in the Python implementation that is an asymmetrical (different) implementation to the C implementation.

We are not interested in running Python on the host, but we want to run C. To some degree it seems to work with the C implementation on the host and target. What features or aspects of the protocol are we missing out on by running the target implementation on the host?

Is it a common enough use case to want C for the host implementation that the C implementation will fully support the host as well as target?
