Don't put this out of context. I'm against doing so in the first (non-normative) sentence in the document. There's a whole section discussing the relationship between RDF and JSON-LD. I'm more than happy to extend that section if anything is missing there.

I'm confused. What do you want? We can either convert RDF data into native types (and potentially loose precision by doing so) or to JSON strings preserving the lexical form. We support both.

So, you would like us to disallow blank node predicates? Is it better that data doesn't show up at all when converting to "RDF" than to have it show up with blank node identifiers? It is easy enough to filter such triples if you want to.

That's a spec bug and was never intended. We throw errors in some places but not all.

Even though I asked you explicitly how you would handle that (and presented three options with pros & cons), you didn't give me an answer. So, again. How would you like to see that handled?
