Is GShade allowed?

[GaiusDrakon]

There was a second thread... I want to say in 2015? ...which linked back to the 2013 thread asking if Tool X and Tool Y and so on were all okay, where a SQEX rep weighed in to note that their reassurance that graphical alterations via post-processing that didn't alter the actual game files were okay was a blanket statement and that people didn't need to ask individually about every single possible tool that let you make graphical alterations via post-processing without altering the game files.

(Unfortunately, as the forum's search tools are terrible, I cannot seem to find that thread to link it here.)

But that was ~7 years ago (or whatever), and the original thread was 9 years ago; the TOS has changed multiple times since then. And moreover, SQEX support themselves noted in a reply to someone that statements like that were very old and did not necessarily apply any longer regardless.

So what exactly IS the status of GShade? I think this is the most important question we all want to know.
