+ *
+ * TODO: field nullability in this class reflects legacy use, and typically would indicate that the
+ * client's intent didn't provide the respective data. In some cases we may be able to provide
+ * defaults instead of nulls -- especially for methods that return nullable lists or arrays, if the
+ * client code could instead handle empty collections equally well.
+ *
+ * TODO: some of these fields (especially getTargetIntent() and any other getters that delegate to
+ * it internally) differ from the legacy model because they're computed directly from the initial
+ * Chooser intent, where in the past they've been relayed up to ResolverActivity and then retrieved
+ * through methods on the base class. The base always seems to return them exactly as they were
+ * provided, so this should be safe -- and clients can reasonably switch to retrieving through these
+ * parameters instead. For now, the other convention is still used in some places. Ideally we'd like
+ * to normalize on a single source of truth, but we'll have to clean up the delegation up to the
+ * resolver (or perhaps this needs to be a subclass of some `ResolverRequestParameters` class?).
