What plans if any exist in the roadmap to allow PostGIS to support
3D geometries as filter geometry in 3D spatial filter operations
using functions like ST_Within etc.?
My search seems to indicate no evidence of such plans:

Can someone from dev team please share any insights. Thanks.
There's no plan (right now) to support spatial functions and operators
for 3D in PostGIS.
And mainly for theses reasons:
- The only specification who deal with such notions is still in draft
stage (SQL/MM)
- GEOS (who handle topological operations) is 2D only
- Such features will need appropriate funding.
