 // IExportShallow encodes "shallow" export data for the specified package.
 //
+// For types, we use "shallow" export data. Historically, the Go
+// compiler always produced a summary of the types for a given package
+// that included types from other packages that it indirectly
+// referenced: "deep" export data. This had the advantage that the
+// compiler (and analogous tools such as gopls) need only load one
+// file per direct import.  However, it meant that the files tended to
+// get larger based on the level of the package in the import
+// graph. For example, higher-level packages in the kubernetes module
+// have over 1MB of "deep" export data, even when they have almost no
+// content of their own, merely because they mention a major type that
+// references many others. In pathological cases the export data was
+// 300x larger than the source for a package due to this quadratic
+// growth.
+//
+// "Shallow" export data means that the serialized types describe only
+// a single package. If those types mention types from other packages,
+// the type checker may need to request additional packages beyond
+// just the direct imports. Type information for the entire transitive
+// closure of imports is provided (lazily) by the DAG.

 // No promises are made about the encoding other than that it can be decoded by
 // the same version of IIExportShallow. If you plan to save export data in the
