Would be nice to add the url to the relevant spec (if you have it) for future reference.

I wish I knew.  This is non-normative in the SharedArrayBuffer spec itself; in fact it doesn't mention a transfer list at all and refers to the fact that there is "general agreement" about how it should work.  Somewhere else there is a discussion that led to the current consensus, but I'm having a hard time finding it.  It was probably on github.
