Traffic-aware pre-rendering with Eleventy

[Ryuno-Ki]

This is an idea I want to throw into the community to see your reactions :)

When I watched The Primeagan on Next.js' Cloudflare flavour I was wondering at 4:23 whether it is something that could be done with Eleventy to speed up the builds.

Basically, if a site is not visited, don't build it.
This in turn would require some access logs to process (e.g. using GoAccess to generate it in a JSON) and then have generate specific files on-the-fly (to be subsequently cached). Only those sites that are visited often (say, 90 - 99 % of all visits over a given time period) would be build ahead-of-time.

Like I said, an idea. What do you think?
