@mehrdadh thanks for the review!
Yes, if a Project API method implementation is absent a `TypeError` will be
raised at the server side because the abstract method is not implemented when
the Handler class is derived. Also as per
https://github.com/apache/tvm-rfcs/blame/main/rfcs/0008-microtvm-project-api.md#L363
I understand the implementation for all of the methods are indeed mandatory.
Thus, just as a reference something similar to the following will happen:
```
gromero@amd:~/git/tvm$ tvmc micro create-project --force /tmp/x46
~/scripts/sine.tar zephyr --project-option zephyr_board=stm32f746g_disco
