This is roughly what I was thinking. But CanBeMazimized is specific to the
current case. What I think you want is:

enum WorkspaceWindowType {
  // Windows of this type have their size and location managed in some way.
  WORKSPACE_WINDOW_TYPE_MANAGED,

  // Windows of this type float across all workspaces.
  WORKSPACE_WINDOW_TYPE_PERSISTS_ACROSS_ALL_WORKSPACES,

  // Windows of this type are completely unmanaged by the workspace code.
  WORKSPACE_WINDOW_TYPE_UNMANAGED,
};

WORKSPACES_WINDOW_TYPE_PERSISTS_ACROSS_ALL_WORKSPACES replaces
SetPersistsAcrossAllWorkspaces.
WORKSPACE_WINDOW_TYPE_UNMANAGED replaces SetTrackedByWorkspace.

In addition to a setter/getter you'll need a SetDefaultWorkspaceWindowType which
replaces SetDefaultPersistsAcrossAllWorkspaces.

+ASH_EXPORT bool GetCanBeMaximizedByWorkspace(const aura::Window* window);
+
 // Makes |window| persist across all workspaces. The default is controlled
 // by SetDefaultPersistsAcrossAllWorkspaces().
