As for bb's absence (I don't mind saying it) I sometimes cringe at his direct methods of presenting things, but I sympathise with the following view...

If we have some software that we know to be flawed - in this case, inaccurate shaders operating in non-linear colour space - and we have the means to eliminate that flaw, why in heaven's name would anyone NOT want to do so?

Well, here are several perfectly good reasons to be going on with:-  I don't understand it; it's more effort than it's worth; it's an unnecessary complication to my workflow; etc. For what little it's worth, I personally have no argument with any of those reasons. (It's easy for me - I positively want all my shaders to be linear, and that's why I use Pro).

Then there are the not-so-good reasons: I don't like anyone telling me what to do, so I'm not going to do it; I'm going to tell everyone else that it does nothing but mess up my renders even though I don't understand why.
