We = this community.
Why not = I don't have a big data crawl infrastructure in my basement :-)

So where are all the agents? [1]

Clients are the thing to invest in.

It's certainly not desirable indeed.
Don't get me wrong, I'm not advocating that
everybody should only use Schema.org andJSON-LD.
However, if we did, interoperability would be much better
(at the cost of diversity, which would be a bad thing).

This shows that heterogeneity and Postel's law are indeed in conflict;
but, like you, I see the solution in embracing that heterogeneity,
not in following Postel. Yet that comes with additional complexity.

…but there are limits with regard to completeness and time
depending on the server-side interface (LD documents, SPARQL endpoint, …).
And currently, there are far less limits for harvesters
compared to individual consumers,
so this is why we should enable the latter group through tooling.

Best,

Ruben
