And the flip side of that with YAML is you can stream it, but you don't know once you've gotten to the end if it was the whole document without some user defined checksum mechanism.

I believe that's only true if one were to load YAML via the "SAX"-style per-event stream, and not the "object materialization" that normal apps use (aka `yaml.load_all` or JAX-B objects) since in those more data-object centric views, where would one put the processing events for those markers?
I also originally expected `yaml.parse(...)` to eat them as it does for comments and extraneous whitespace, but no, it does in fact return dedicated stream events for them, so TIL
