Comment (by strk):

 So it turns out Geometry#setSRID is supposed to be only used in
 exceptional cases, for backward compatibility:
 https://github.com/locationtech/jts/blob/master/modules/core/src/main/java/org/locationtech/jts/geom/Geometry.java#L264

 Rather, a user should indeed set the SRID in the factory, which we're not
 doing from C-API.

 Now that we DO have garbage-collected factories (for precision model) we
 might start doing something about SRID too. Sounds like a wider plan is
 needed though.
