I don't think so, and I want some back proof on that.
Also, note that, OoT lacks lots of things to be considered the Imprisoning War.
There's no army of thieves,he doesn't obtain the full triforce, etc
Yes, but if OoT was the IW, and the maidens were descendants of said sages(like it is said through the game), there would have to be a Kokiri maiden, a Goron maiden, etc
The SNES manual was retconned, and i don't think that FSA is a direct sequel of MC and FS.
It doesn't have nor does it need to be.
The re-release of alttp also helped to prove that OoT can't be the Imprisoning war, due to the nature of the sages
The maiden's are descendants of the sages, so, it makes sense if they are the same as in ALttP.
You can assume that, FSA is, at least in part, the BS of ALttP, as most of the events in it kinda lead to the events in ALttP
