Comment:

 It's because some required operations was not implemented for this CS. In
 this case (`remove()`) `covered_by()` was not implemented. It should be
 fixed in 1.61 at least for Points and Boxes, see:

 https://github.com/boostorg/geometry/pull/345


 This bug should also be fixed in develop and master branches so you could
 pick the library from the repository if you need it now.

 Furthermore, some other algorithms might not work correctly for some cases
 in 1.60, e.g. when an rtree spanned across more than a half of a globe
 (bounds width >= 180deg) or when stored boxes could cross antimeridian
 (e.g. longitude min-max = 170-190). So spatial predicates might not work
 correctly in such cases.

 So yes, it basically means that in 1.60 you could e.g. calculate boxes
 with `bg::envelope()` in geographic but then convert boxes to cartesian
 and store them in the rtree. And if you know that boxes could cross
 antimeridian perform some of the queries near the antimeridian 2 times,
 one for negative coordinates near -180 and the second one for
 corresponding coordinates greater than 180.
