Your lack of (self-)education and inability to quote properly are your 
problems alone.

As long as Opera is officially documenting that on their website, and are 
giving no end-of-life dates for their browser versions, I will (have to) 
consider that a non-safe version of that implementation.  For example, they 
have recently removed the documentation for pre-Elektra (6.0) versions, so 
those are considered safe by me.

Opera cannot seem to decide when to call their implementation "JavaScript" 
and when "ECMAScript".  However, the term "Opera ECMAScript" describes their 
implementation better as it is more distinctive from others and the 
implementation is closer to ECMAScript than to (Netscape/Mozilla) 
JavaScript.

There is not much "etc." beyond that.  Name at least one implementation that 
you deem important and I will consider them.

I have mentioned JScript at least once in the part that you conveniently 
snipped.

Incorrect.  Unfortunately, Microsoft has joined the recent trend for 
confusing oversimplification and impreciseness there (which is not atypical 
for the MSDN Library, though).  However, the documentation for JScript 
starts at <http://msdn.microsoft.com/en-us/library/hbxc2t98(VS.85).aspx>, 
titled "JScript (ECMAScript3)" and <http://msdn.microsoft.com/en-
us/library/4yyeyb0a(VS.85).aspx>, titled "JScript User's Guide (Windows 
Scripting - JScript)".
