The OSM API's main purpose is two way data transfer in small chunks.
Since you modify the geometry this rules out any editing and
transferring data back.
For rendering/viewing your concept hinges on the idea that dropping
nodes is a good way to simplify geometries for rendering purposes which
is not generally the case. Or in other words - you assume that your
error metric accurately describes the perceptual error when viewing the
rendered geometry (which is evidently not the case).
