It think it would be better to create a Pull Request even if the work is
not complete.
This way others will be able to comment on the changes and everyone here at
dev@ will see the comments.
At the moment it is possible to comment on your commits (in your repo) but
then only you will receive the feedback.
With [2] it is much easier to see the whole diff but it is not possible to
comment on it.
