 Replying to [comment:2 strk]:

 "precision" an information of the geometry objects themselves to speed
 things up.

 Easy to say, not so easy to design and implement in a clean, clear and
 consistent way.  I'll look forward to an RFC to indicate how this would
 actually work.

 Precision handling doesn't seem to be a big pain point for most PostGIS
 users.  It seems like it is mostly a problem in the Topology subsystem.
 So perhaps it should be designed and built there first, and then can be
 extended to other areas when it's proven out.
