Blog post author here -- I wasn't totally clear, but what I meant was that we didn't have the capacity to do the work to make Notion fully cross origin isolated (which would have indeed worked on all the major browsers). That meant we could only roll it out on the browsers that provided this temporary workaround for it.
Aha, that makes sense. BTW, i would like to reach out to you to discuss, if you like, your corruption cases and pain points so that we can improve upon them. i don't see a way to get in direct touch with you, but if you are up for such a discussion, please email a contact address to stephan at sqlite org.
