Like kup0 also just guessing, I would assume they would have eventually made this private so that porch pirates had less information available to target victims. If a login is required that opens possibilities for rate limiting and easier abuse detection. This could also be to rate limit 3rd party businesses scraping their data. I could be giving them too much credit. [Edit] Thinking this through a bit more, this could also be to funnel 3rd party businesses into paying for authenticated access to an API and perhaps even pay for different rate-limit plans.
