I agree wholeheartedly. The only change is internal to these organizations (eg: CloudFlare, AWS) Improvements will be made to the relevant systems, and some teams internally will also audit for similar behavior, add tests, and fix some bugs.
However, nothing external will change. The cycle of pretending like you are going to implement multi-region fades after a week. And each company goes on continuing to leverage all these services to the Nth degree, waiting for the next outage.
Not advocating that organizations should/could do much, it's all pros/cons. But the collective blast radius is still impressive.
