EB2 will not contain emergent factions, Jewish or not. The Jewish revolt could be very well simulated with normal unrest. It was not as if the Hasmodean state had imperial ambitions.

Unit roster is not very relevant when discussing faction inclusion. The main point is whether they were important and expansionist (i.e. cannot be simulated by rebels). And the Maccabean revolt, important as it later became from a religious perspective, was from a contemporary point of view just one of many Seleucid provinces breaking away. A potential Pontus they were not.
