There's not a whole lot that can be done to combat this, but I suppose Apple could do something like keep a database of known tracking URL patterns and when encountering such URLs, "unwrapping" them in an isolated background webview which is fully generic across machines and doesn't have the user's cookies or other data, which would limit the information gathered, and then finally passing the untracked URL back to the user's webview instance. EDIT: They could also do something similar to what they've done with Content Blocking Extensions, maybe call them "URL Cleaning Extensions", which allow third parties to maintain tracking URL pattern lists which Safari can then follow to do its unwrapping.
