In that sense it is the same question really: How does auto-revoking
work? (I suppose the "orthogonal" bit is what the default should be
and whether it can be changed from what is currently the default, but
if we cannot change the current "broken" default I find it hard to
image anyone ever opting into the other model.)

Without details on the specifics, it's hard to reason about this
model. E.g. when are

  <div>.style.backgroundImage = "url(" + url + ")"
  <img>.src = url
  <img>.srcset = "1x" + url + ", 2x " + url2"GET", url)
  <style> body { background:url(url) } </style>
