I think the thing to do here might be to add `sql` and `params` arguments to a bunch of the plugin hooks, such that they can see the main query that is being used on the page that they are helping to render.

While I'm working on this: https://docs.datasette.io/en/0.62/plugin_hooks.html#register-output-renderer-datasette output renderer functions take `sql` but do not currently take `params` - they should also take `params`.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1384273985,

I'll start by implementing the first set, then I'll think further about those ""maybes"".","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1384273985,

So I would have to pull the `sql` and `params` variables out of the `context` since they are not being passed to that method. OR I could teach that method to take those as optional arguments.

Might be an opportunity to clean up this hack:

```python
async def render_template( 
     self, templates, context=None, plugin_context=None, request=None, view_name=None 
 ): 
```
Where `plugin_context` is a special dictionary of values that can be passed through to plugin hooks that accept them - so `database`, `table`, `columns`, `sql` and `params`.

Those would then be passed when specific views call `render_template()` - which they currently do via calling `BaseView.render(...)`, but actually the views that are used for tables and queries don't even call that directly due to the weird designed used with `DataView` subclasses that implement a `.data()` method.

So yet another change that's blocked on fixing that long-running weird piece of technical debt:
