I've been slammed with work/personal stuff so haven't been able to actually prototype anything with this. :(

tl;dr: I think this would be useful immediately as is. It might also be nice if the plugins could return `Promise`s.

The long version: I read the design notes and example plugin. I think I'd be able to use this in [datasette-ui-extras](https://github.com/cldellow/datasette-ui-extras) for my lazy-facets feature.

The lazy-facets feature tries to provide a snappier user experience. It does this by altering how suggested facets work.

First, at page render time:
(A) it lies to Datasette and claims that no columns support facets, this avoids the lengthy delays/timeouts that can happen if the dataset is large.
(B) there's a python plugin that implements the [extra_body_script](https://docs.datasette.io/en/stable/plugin_hooks.html#extra-body-script-template-database-table-columns-view-name-request-datasette) hook, to write out the list of column names for future use by JavaScript

Second, at page load time: there is some JavaScript that:
(C) makes AJAX requests to suggest facets for each column - it makes 1 request per column, using the data from (B)
(D) wires up the column menus to add Facet-by-this options for each facet

With the currently proposed plugin scheme, I think (D) could be moved into the plugin. I'd do the ajax requests, then register the plugin.

If the plugin scheme also supported promises, I think (B) and (C) could also be moved into the plugin.

Does that make sense? Sorry for the wall of text!","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1651082214,
