This is a very interesting subject indeed. I would be interested
in solving spatial indexing in generic way myself.
(I'm sorry for constantly referring to GIS domain,
an occupational disease, clearly.)
From GIS domain perspective, regarding persistent spatial index, I've
observed popularity of two solutions based on Open Source implementations:
- PostgreSQL GiST as foundation of spatial index for PostGIS 
- simple single file-based (.qix) quadtree index  and

I am not a member of Mapnik team, however I have spoken to Artem
Pavlenko long time ago about generic geometry library and he
was confirming high interest in this subject.
In those times, the only usable alternative for GIS was GEOS.
Artem was not very enthusiastic about using GEOS. Given that,
I would assume Mapnik project would be a potential user of GGL.
