Questions:
- What if we added something to HTTP where if you're only fetching a page to read OpenGraph tags, you send a special header saying "I only want the OpenGraph data", and the server then has the option of sending only the <meta> tags and nothing else?
- Could this help with the Mastodon "hug of death" (because the server can generate a simpler version of the page, caches can behave differently etc) where many instances rush to generate preview cards driving the previewed site offline?
