/**
 * Choosing what to put in a column.
 *
 * ── One option is still a choice worth showing ──
 *
 * I had argued the opposite: Free Text is the only kind that works, so opening the editor straight away
 * saves a click that asks to be got past. That was wrong in the way a shortcut usually is — it optimised
 * the state of the app today and hid the shape of it. Somebody adding a component cannot see what a
 * component IS, or that there will be others, and the day the second kind lands the interaction changes
 * underneath them.
 *
 * It is also the pattern this admin already uses. The nav lists unbuilt sections as `soon` rather than
 * hiding them, on the reasoning that a nav showing only what is finished gives no sense of what the
 * thing is for. The same argument applies here.
 *
 * ── The list is in the plugin, not the API ──
 *
 * The API decides what may be STORED — `free-text`, today. This decides what may be OFFERED, and it has
 * to live here because every kind needs a label, an icon and an editor that only exists in this plugin.
 * A kind the server would accept and this has never heard of is not creatable anyway.
