Is anybody using LO's JavaScript editor window?

[Stephan Bergmann <stephan.bergmann@xxxxxxxxxxxxx>]

For each of BeanShell and JavaScript, we support some edit window in 
which such scripts can be typed in and modified, and from which those 
scripts can be run.  (For example, under "Tools - Macros - Organize 
Macros - JavaScript..." select "Macros - Application Macros - Hello 
World - helloworld.js" and click "Edit".)  For Python, on the other 
hand, we do not offer such an edit window at all.

Now, how widespread is the use of this edit window feature for 
JavaScript, actually?  Does anybody use it, would anybody miss it? 
(This is only about the JavaScript feature, the BeanShell edit window is 
not affected.)

I'm asking because I have 
<https://gerrit.libreoffice.org/c/core/+/165190> "Update to latest Rhino 
1.7.14" as a potential master change.  But, as its commit message says: 
"Update [...] at the expense of losing, at least for now, the script 
editor for it (which had been hacked into the old upstream sources in a 
hard-to-maintain way)."

(And, in turn, the reason why I'd like to update Rhino is because I have 
a JS script that our old Rhino 1.5 just can't comprehend.)
