I'd be willing to accept the aetheric bending of light to a degree, so long as they agree to pretty much what was mentioned... that even the slightest disturbance would make it go away. In other words, no mystical voices on the wind or ability to stab or attack WHILE invisible. Moving, speaking or any other shock, as was said, would instantly drop the aetheric control, imo.
I, unfortunately, have already run into some RP where the people in question were in a fairly obvious position when they were stealthed and then acted as a voice on the wind. For the sake of continuing  on with the RP, I shrugged it off... but in a combat situation... I wouldn't let that fly. A rogue/ninja needs to be in the shadows, behind crates or other covering, or be entirely focused on controling their aetheric invisibility, imo. Otherwise it becomes a bit too unfair to their victims.
^ This is my take on it too.
Also, some of this has already been stated, but there are many other ways to detect people.
- Scent (Especially for Miqo'te).
- Footprints, or effects of feet on the terrain.
- The invisible body obstructing the breeze/wind.
- Sounds of breathing, and/or movement; such as clothes, or feet meeting the ground (Especially for Elezen).
These would be minimized at a distance, but when the invisible person gets close, it gets easier for things to get noticed.
Another thing is, if a character can detect aether, and the stealth ability uses aether, they should be able to detect the aether-stealthed person. Then again, I am not familiar with lore on aether detection.
