The phenomenon of lingering aether is also something that the Monks of the Fist of Rhalgr take great advantage of in their training. As mentioned, when some one dies violently, their aether disperses into the land around them and doesn't return to the lifestream. As such, the lands of great bloody battlefields are actually coursing with Aether.
Monks seek these battlefields out to train and meditate on, as they can in turn absorb the remnants of aether in order to help open their Chakra.
Also as mentioned, the flashier deaths of people poofing into aether are generally special circumstances that already deal heavily in aetheric influence. I imagine in a normal death, one's aether slowly seeps away in a silent fashion. Much like how aether itself is more or less invisible unless being acted upon, the aether leaving one's body likely dissipates at a level that cannot be seen by the naked eye.
