Comment(by dbaston):

 Discussed on IRC....nothing wrong with using GEOS STRTree per se.
 Aggregates can cause headaches for upgrades, since they can't be dropped
 if there are views that depend on them.  Clustering functions could be
 changed to be be standard functions that accept geometry[] as an input
 type, if PSC wants to avoid creating new aggregates.  User would call
 ST_ClusterIntersecting(ST_Accum(geom)) or similar.
