> If you're going to use a locally modified network Except (correct me if I'm wrong), this is not a "modified network", it can be another disconnected network that's just as "correct" in the standard conformance aspect as the Internet. It's more like Chrome is "modified" to support one network better than others - or rather, to possibly break on other networks. In fact, it seems to me like the very idea of HSTS preload list isn't friendly with UAs working on multiple separate networks. But yeah, you're right that this is what they are designed for after all. (I'm also probably slightly biased, since some of our test environments use .dev domain in our LAN.)
