You could call it that, yeah.
If you were feeling uncharitable, you could say that the "lack of status regulation emotions" thing is yet another concept in a long line of concepts that already had names before Eliezer/someone independently discovers them and proceeds to give them a new LW name.
you could say that the "lack of status regulation emotions" thing [...] already had names [...]
It's sillier than that. It's attempting to invent a new, hitherto undescribed emotion to explain behavior that's covered perfectly well by the ordinary vocabulary of social competence, which includes for example words like "tact". There are also words to describe neurological deviations resulting among other things in a pathological lack of tact, but they too have little to do with emotion.
(Strictly speaking, there are status-regulation emotions, and they are called things like shame and envy. But that clearly isn't what Eliezer was talking about.)

I guess there'll be a fair bit of traffic coming from people looking it up?
