Sure, weak referencing is probably not well explored approach, but
the underlying idea applied to blob is interesting: URL creates no
reference to Blob (from GC perspective), meaning Blob is subjected
to GC regardless of BlobUrl existence. This would remove the need
for revoking URL, programmers would only need to maintain blobs
they want to be persistent (e.g. in some global array).
Weak referencing is pretty well explored, I think. It's intentionally
not supported for the most part in JavaScript, because most weakref
features expose garbage collection behavior to scripts. Web APIs
don't do that.
This approach exposes GC behavior, making it possible to write code
that behaves differently depending on GC.

The point was not to talk about weak refs, but about not creating a GC
reference from URL to Blob
