It’s not really relevant in 2025… The HTTPS negotiation is going to consume the initial roundtrips which should start increasing the size of the window Modern CDNs start with larger initial windows and also pace the packets onto the network to reduce the chances of congesting There’s also a question as to how relevant the 14kb rule has ever been… HTML renders progressively so as long as there’s some meaningful content in the early packets then overall size is less important
