Pageviews should be unique when Cloudflare's under attack mode is on

We can check this with ?__cf_chl_tk=... in the referrer URL.

That would be great!

If I am not mistaken, if we include the SimpleAnalytics script on the "under attack" page, the script is not executed at all. It is okay, as the opposite would systematically add one page view to each session.

I investigated a bit more on the second page (the one loaded after the redirection from the "under attack" page), and it receives a referer [sic] header server-side, and the value includes the original external source. This header seems to be be added by Cloudflare when calling the backend, and does not provide the same value as document.referrer (which is not the original, but the __cf_chl_tk= one)

Maybe a solution would be to force a specific referrer when loading the script, the same way you do the overwrite domain name, such as a data-referrer attribute? The advantage of that solution is that it is provider-agnostic, and it includes the original referrer instead of an unknown one.
