I can't access the issue tracker, so I'm replying here.
What's the use case for this?  As far as I can tell, everything that
Structured Clones support is either 1) easy to serialize into JSON, 2)
expensive to serialize, or 3) silly to serialize.

An example of 2 would be ImageData.  An example of 3 would be RegEx's.  File
and FileData would fit either in 2 or 3 depending on how you implemented
them.

My point is that I don't see a strong reason why Structured Clones would be
useful outside of the browser.  And thus I'm not sure it's worth the effort
to create a standardized way of serializing it.

But maybe I'm missing something?
