In other words, why there is not

Yes, not yet there and it is a good idea.

good, some times I ask just to not repeat code and to understand better the library.

And it indeed this adaptation of boost::array is not included in the
library, what steps should I follow to make a boost::array adapted to
GGL?

Adapting to the Point Concept is necessary, which is actually not hard. Most samples use registration macro's, which is probably not possible here. So perhaps the c05_custom_point_pointer_example.cpp gives the idea. Basically you have to specialize the tag, coordinate_type, coordinate_system, dimension metafunctions (all trivial) and the access structure, also not too hard.

In case you start with this, I'm interested in the result, for incorporation. Otherwise it will probably be included as well but then it might take longer.

sure, you will find these files attached:

boost/geometry/geometries/adapted/boost_array.hpp
boost/geometry/geometries/adapted/boost_array_cartesian.hpp
boost/geometry/geometries/adapted/boost_array_geographic.hpp
and
geometry_boost_array_test.cpp

Feel free to incorporate it in Boost.Geometry. I am working in a fusion adapter too. This is very useful to me because I do most of the (cartesian) geometry related stuff with boost::array<double, N>

Thank you,
