The plan is still there. We have an implementation, as you know, and
want to revisit it a little more than we did until now. So it is
currently not included, also because it is not yet used in the
algorithms, so not yet essential.

As Mateusz said, we want to have an implementation based on templates;
the SOC version did use virtual methods and we wish to avoid them.

People should not complain the way they did. We will take care for good

The implementation we have is r-tree. If the implementation you refer to
is completely template based and has no virtual methods, we're certainly
interested to compare or even include it. Our actual wish is a Priority
R-Tree because it is worst-case optimal.

We're currently not planning persistent trees inside the library (though
it is interesting of course). We could do research to combine them (e.g.
based on our concepts), so interfacing indeed, but that might more have
the form of an external-sample than real integration.
