I don't quite understand this question.
There is a section in the frames proposal titled "Frames and JSON"
which mainly just presents a table

	JSON		Erlang
	null		null
	false		false
	true		true
	numbers		numbers, but JSON has no integers
	strings		binaries
	arrays		lists or tuples
	dictionaries	frames

The implied mapping takes JSON {id: 4135, title: "title2"}
to <{id ~ 4135, title ~ <<"title2">>}>.

The bounded size of the Erlang atom table is a vulnerability
but there is an EEP to address that; that in itself is a much
more urgent issue than frames.
