Hi thank you very much for providing this library.

While updating to 2.1.0 we noticed that now

from shapely import Point
from shapely import to_wkt

to_wkt(Point(0.000000001, 0.0))
# 'POINT (1e-9 0)' in version 2.1.0
# 'POINT (0 0)'    in version 2.0.7

I'm not sure what the specification says about that case, but for us it broke our sqlite integration.

Thank you for looking into this.
