You don't have to push immediately to review: you commit a few commits locally, until you're sure of the architecture. Once you're sure, start pushing the earlier ones out to review. If you're really unsure of the design, then tackle that in a design doc first. Discuss what the API will look like, write out sample call sites to show its use. Otherwise, yeah, you'll probably end up re-writing it. Small commits have another benefit: they can be moved (cherry picked, for example to backport) or reverted easily.
