...I assume the implications are that:
1. this service will scale to meet request load without QoS degradation (i.e. it's probably running on FaaS infra), rather than being a fixed-size slowly-elastic cluster that would get choked out if your downstream service got popular and flooded it with thousands of concurrent requests
2. you can directly take the URLs the service spits out, and serve them to your downstream service's clients, without worrying much about deliverability, because there's an object store + edge CDN involved.
In other words, it's not just a single headless-chromium instance running on a box somewhere; you could actually use this thing as an upstream dependency and rely on it.

Given that the author's imagined use-case is giving non-multimodal LLMs a way to emit visuals (the prompt at the bottom of the page starts "When asked to create visuals, charts, or mockups"), I think their idea is that the resulting rendered images would more-likely-than-not only be requested once, immediately, to display the result to the same user who caused the prompt to be evaluated.
Where, in that case, the metric of concern isn't "time+bytes cost for each marginal fetch of the resulting image from the CDN"; but rather "end-to-end wall-clock time required to load the HTML in the headless browser, bake the image, push it to the object store, and serve it once to the requesting user."
OptiPNG would slightly lower that last "serve it once" cost, but massively inflate the "bake the image" time, making it not worth it.
(I suppose they could add image optimization as something you could turn on — but "image optimization at the edge" is already a commodity product you can get from numerous vendors, e.g. Cloudflare.)
