Well, I think the timeline would have it being connected to the Grimm rather than the Faunus. Oobleck's description of the Faunus War makes it sound relatively recent, as opposed to it being like a hundred years ago. My opinion is that the Faunus War probably concluded around the time most of the students were born. Something that ended around when they were born would certainly seem like "ancient history" to teenagers. It would also make sense with regards to the timeline for the White Fang.

From the commentary we do know that the war between the Grimm and the humans was not some rapid shift. It is likely that, before the discovery of Dust, humans fought them with significant casualties, but were still able to build fortress cities in places like the Emerald Forest and preserve themselves. No telling how long after humanity appeared that the Grimm would have attacked. It seems likely that humanity would have built up somewhat significantly beforehand in order to avoid extinction until the discovery of Dust, so I would suggest at least a few centuries of peace before the appearance of the Grimm.

They were facing extinction in the long-term until discovering Dust, but merely discovering it would not cause a sudden victory. The war between the Grimm and humans could have been something that was waged over many centuries or longer with it only entering a somewhat decisive phase around the time Jaune's great-great-grandfather was alive.

You could see it as being a bit like Attack on Titan where humans have had a century of relative peace due to their widespread application of Dust and formation of Hunter units to keep the Grimm at bay and that peace is now set to be disrupted.
