Why is GL.IssuePluginEvent not listed on documentation page for "GL" class?

Here is the current documentation for "GL.IssuePluginEvent":

http://docs.unity3d.com/ScriptReference/GL.IssuePluginEvent.html

The top of that page has the following message:

"Obsolete
IssuePluginEvent(eventID) is deprecated. Use IssuePluginEvent(callback, eventID) instead."

However, this page describes both forms of the function, the obsolete version and the new version:

public static void IssuePluginEvent(int eventID);
public static void IssuePluginEvent(IntPtr callback, int eventID);

Note that the second form is the newly introduced function which is making the other function obsolete.

The following is the current documentation page for the "GL" class:

http://docs.unity3d.com/ScriptReference/GL.html

Notice that "IssuePluginEvent" is not listed on that page!

Meanwhile, the "UnityEngine.Rendering.CommandBuffer" documentation page does include the function "IssuePluginEvent":

http://docs.unity3d.com/ScriptReference/Rendering.CommandBuffer.html

So, I am wondering whether there is a plan to remove "IssuePluginEvent" from "GL" entirely, or if the omission of a link to that documentation page was some kind of mistake (e.g., because the other form of that function has been marked obsolete, the whole page was de-listed from the "GL" class page).

Can someone from Unity comment on this?
