Just how responsible for the Flood of Light was Hydaelyn?

[Absimiliard]

Also keep in mind that the source of this information is Elidibus, who has a vested interest in having Dark triumph over Light. His comments on the matter are less about "Stop or there'll be a Flood!", more about "Stop or we can't win!" As shown by Emet-Selch's disdain for the Light-infested territories of Norvrandt, Light is also anathema to them.

I'm still waiting for Lahabrea's ominous warning from 2.0 to be clarified... given as most everything else has been.

Urianger has also expressed concerns for the state of the balance. While I would tend to take what Elidibus and Lahabrea say with a grain of salt until proven or disproven, we know that Urianger is an exceedingly well learned individual that has the Source's best interests at heart.

As for Lahabrea... I'm beginning to wonder if SE didn't just sweep him under the rug at this point. It's pretty likely that a lot of his hammy writing was the result of them not yet having Ascian lore all that well fleshed out. Ascian appearances throughout 1.0 and ARR typically made them come off as mustache twirling villains of lolderkness. Maybe they'll use the frequent host hopping to explain why Lahabrea seemed to be completely off his rocker? It would be a pretty valid excuse. Emet-Selch already told us of the consequences of hopping bodies too often. What's to say doing it habitually wouldn't lead to psychological damage to go with the severely diminished powers? Anywho, I went off on a tangent, my bad. Tl:dr: Lahabrea was such a nutball courtesy of incomplete Ascian lore that we may never find out what he meant.

this isn't necessarily the case, but what we thought was the case due to our understanding at the time.

And what of Urianger's far more recent comments on the subject?
