New Datasette release: 1.0a33, which finally brings documents the ?_extra= JSON API mechanism and brings it to the row and query pages in addition to the table pages

Users are enthusiastic about the new _extra= JSON API feature in Datasette 1.0a33 because it will make the tool even more flexible, with interest in Claude's contributions to the code.
Since the JSON extras API is a little hard to explain without an example I also had Fable 5 and GPT-5.5 collaborate on this custom API explorer tool for trying out the new feature https://tools.simonwillison.net/datasette-extras-explorer#url=https%3A%2F%2Flatest.datasette.io%2Ffixtures%2Ffacetable.json%3F_size%3D1%26_facet%3Dstate&extras=count%2Ccount_sql%2Cexpandable_columns%2Cfacet_results

@simonw the _extra= stuff is gonna make datasette even more flexible
claude helping ship code is interesting, how much did it write?
@simonw curious if _extra affects query performance or if its just a convenience layer on top
