`GEOSGeometry.json` was using `OGRGeometry.json` prior to 1.9. That was
changed in #25141. Now GDAL is required (#26753) and I believe we should
restore previous `GEOSGeometry.json` implementation for performance
reasons:
{{{
In [67]: ls = LineString([(x, x) for x in range(1000)])
In [68]: %timeit ls.json
10 loops, best of 3: 42.6 ms per loop
In [69]: %timeit ls.ogr.json
100 loops, best of 3: 3.75 ms per loop
}}}
