The EPL is incompatible with the GPL at least , the compatibility
with the LGPL is not as clear.
GEOS incorporating JTS code would make it a derivative work, and require
the code in GEOS be under the EPL as well.
Only clean-room implementations of JTS features can be incorporated in
GEOS without triggering license incompatibilities.

Conservancy is a good idea.
