  "message": "internal/impl: pass ExtensionTypeDescriptor to extensionMap\n\nThe layers freely convert between ExtensionTypeDescriptor (via\nExtensionTypeDescriptor.Type) and ExtensionType (via\nExtensionType.TypeDescriptor()). For certain hot functions , like\n(*extensionMap).Has() and (*extensionMap).Get(), this saves a Type() and\nTypeDescriptor() pair.\n\nOddly, the gains are bigger than I expected.
