 *
 * ```ts
 * const current = BootstrapStack.lookup(...);
 * // ...
 * current.update(newTemplate, ...);
 * ```
 *
 * And do something in between the two phases (such as look at the
 * current bootstrap stack and doing something intelligent).
 *
 * This class is different from `ToolkitInfo` in that `ToolkitInfo`
 * is purely read-only, and `ToolkitInfo.lookup()` returns `undefined`
 * if the stack does not exist. But honestly, these classes could and
 * should probably be merged at some point.
