Supported

The first link[rel=monetization] element in <head> of document at any time is used.
- When the href of first such element is modified, the present monetization endpoint is changed.
- When a link[rel=monetization] element is prepended, it becomes the first tag and the present monetization endpoint is changed.
- When a link[rel=monetization] element is appended, no change.
- When all link[rel=monetization] are removed from the document, monetization is stopped.
document.createElement("link").relList.supports("monetization") // true
monetization-src CSP directive.
Only visible tab is monetized.
The present implementation for "monetization start" and "monetization stop" is essentially "fetch and log details":
- Log the current link[rel=monetization].href (Payment URL)
- Fetch the details at Payment URL with correct HTTP headers (referrer, cache-control, accept) and ensure CORS is respected.
- Validate the response:
  - ensure correct mime-type and it can be parsed at JSON
  - ensure required fields are present
- Log the required field values (or, errors, if any) to JS console.

Not supported

Monetization link tags in iframes [TODO, IN DISCUSSION: Feature Policy, Multiple tags/streams]
Actual monetization and communication of relevant events
Link header support [NOT PLANNED]

Known issues/edge cases:

Changing the rel attribute value from monetization to something else has no effect (the converse is supported).
Need to fix a memory leak when a tab is closed.
