Kautkysim is somewhat still a thing just as bersteinism and even lassalism, just not separate. It was Lasalle that put the cornerstone of today socialdemocracy, Bernstein bastardised marxism to the point of being outwardly similar but opposite in actual idea, and Kautsky propelled that to the socialimperialism.
But it isn't being called Lassalism-Bernsteinism-Kautskyism, it's just being called "socialdemocracy". Most succdems just don't know nor care about their origins. This one is a rare one that do know at least something.
If you list an incredibly specific thing instead of a currently-active political party, you're not a serious leftist and are in fact an online larper.
