`?_facet=...` is one example of a query string argument that causes an extra key - `""facet_results""` - to be added to the JSON even though it wasn't requested by name in a `?_extra=`.

Am I OK with that? I think so.

Actually there's an edge-case here that's worth considering: it's possible to use metadata to set default facets for a table. If you do this for a table, then `.json` for that table will always calculate and return those facets - which may be an expensive and unnecessary operation.

So maybe we don't include `facet_results` in the JSON unless explicitly asked for in that case, but have a rule that `?_facet` implies `?_extra=facet_results`.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",323658641,

One solution right now is to define a SQL view for the things that you DO want people to be able to see, and then use Datasette's permission system to hide the tables (`'""allow"": false` in metadata for each table) but show the views.

If you want to redact specific columns there's a plugin for doing that: https://datasette.io/plugins/datasette-mask-columns

This does make sense as more of a core Datasette feature though - tagging it as a feature suggestion.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1531991339,
