I had previously dismissed supporting semi-round displays when developing my chronograph watchfaces. But due to the popularity of the Aerospace+H and Endurance watchfaces I decided to give it a shot.  These now support Forerunner 230/235/735XT models.  The results were not too bad.  Now, due to the smaller memory capacity of these models, unfortunately the feature set is much reduced from the original watchface.
