Preparing geometry is useful when you repeat spatial operations on a geometry, as required, calculated, information needed for said operation is cached. See https://blog.cleverelephant.ca/2008/10/postgis-performance-prepared-geometry.html
The open question is if/where we check for the remaining GDAL ogrhaspreparedgeometrysupport method in all these calls. Maybe a warning on init? I'm not sure what happens when a non-Yggdrasil GDAL doesn't have prepgeom support.
