We all hate #LinkRotting, right? URLs becoming inaccessible because websites are restructured, blogs deleted, software docs refactored etc. #DeadLinks

Why don't we put a JSON feed in .well-known to tell subscribers when URLs change, possibly even in advance?

For example, if you plan to move your blog from you.example/blog to blog.example.com, you could issue this warning:

{
"action": "move",
"source": "/blog/*",
"destination": "blog.example.com/*",
"date": "2026-01-01"
}
