Has any variant had so stable and successful a run as JN.1 and its nominal proles (Ex: JN.1.1.1.1, JN.1.1.1.4, etc)? That it is popping those nominals shows that it is likely still evolutionarily unstable, but its kids just can't gain any traction. Of course, that's just a finger to the wind assessment, but it is starting to seem strange. We've seen variants conquer the globe, but never seen one hold the globe like this...
(I think. Stats might prove me wrong)
