Can you explain more in detail about the backwards incompatibilities
and how to soften them? What's going to break and what are the
specific options?
Hi Sean,
In the C++ and C API there are no backwards incompatibilities but the
get/setCoordinateDimension() methods become deprecated since XYM and XYZ
have the same dimension. Is3D(), IsMeasured(), set3D(), and
setMeasured() should be used instead.
I don't know about the other drivers but Shapefile driver currently
reads XYM geometries as XYZ and that will be changed so that XYM are
read as XYM. I think that is the only incompatibility. A new open option
MEASURE_AS_Z=YES/NO (or something) can be defined for backwards
compatibility. Similar option can be defined for other drivers if they
have the same feature.

ps: Sorry for the late answer, I was offline the weekend.
