I can't remember if it was a translation from Japanese or another language, a Dev post or something form a producer letter or live interview. The general gist was that the current coding of linkshells makes it too difficult in those "few simple lines of code" to make LS management tools. They have planned for the systems to be in place in 2.0 so they are working on other things in the meatime.

Like i said, can't remember exactly and don't feel like spending hours looking it up for you.
