[boost] [GIL] interleaved_ptr as part of API?

Hi, I wonder, why the definitions of interleaved_ptr [1] and and interleaved_ref [2] are provided as examples, instead of included as part of the Boost.GIL API? IMO, these make useful general-purpose utility and it could be easily copied into <boost/gil/utilities.hpp>, couldn't it? Or, into official set of Boost.GIL extensions, at least.
