Comment:

 The ticket has been solved as part of GitHub PR 334:
 https://github.com/boostorg/geometry/pull/334


 Details:

 Empty lines and empty polygons as considered as invalid geometries. As
 such the result of is_simple is irrelevant. In the current fix (see PR
 above) is_simple returns false for both these geometries.

 On the contrary empty multi-geometries are considered as valid (in reality
 representing the empty geometry), and with this bug fix they are
 considered as simple as well.
