And as far as I know, the repo only lists domains that they've successfully circumvented, is that correct?
Well, yes and no. Most of them are not circumvented, but list a link to some internet archive that has the full text for search engines. So this list is actually a general list, not a specific "we can circumvent this with tricks".
Could Kagi have its own list, with other conditions?
I am not so sure about that. From Kagi's perspective, this seems like a lot of development costs. You have to maintain this list, make a repo for it, accept pull requests, etc. What percentage of paywalled articles is enough? 30%? 50%? What if only specific topic (politics? sports?) are paywalled? It just seems like an impossible tasks to do "right".
