We don't depend on these, we have our own :/ The real answer for a GIS system is to have an explicit tolerance parameter for calculations like distance/touching/containment, but unfortunately we didn't do that so now we have our own compatibility/boil the ocean problem if we ever wanted/were funded to add one.
Well it sounds like what's currently happening in Postgres is probably going to change, so how might we structure that to help PostGIS? Would simply lopping off the last few bits of the significand/mantissa work, or is that not enough when different GRSes are involved?
