Though we don't really know what a rejoining would feel like, or if it would feel like anything at all. Maybe a regular person with average sensitivity to aether wouldn't even notice, but someone with high sensitivity would? Or the extra aether wouldn't even register for Eorzeans, given that we were told in the opening of ARR that there's so much ambient aether there that it sometimes makes foreigners ill when they first arrive (though I don't recall that ever coming up again, several rounds of foreigners arriving in Eorzea later...)? Maybe you just wake up one morning feeling better than normal, and just chalk it up to 'waking up on the right side of the bed'.
Yeah, Una Tayuun was a former member of the Path of the Twelve, and so I think implied (or stated outright) to have the Echo. It's implied that her memory issues are due to the magical shenanigans involved in Louisoix's spells at Carteneau, which don't actually have any lore precedent other than "it was convenient for the plot", so I don't know if it's meant to be a major plot point for the future.

But mostly I was going off the short story with Alphinaud and Alisaie, where they only really reacted to watching Dalamud "disappear", and didn't feel anything other than regular emotions relevant to that event (joy at Dalamud's fall apparently being stopped, anxiety that something was still wrong). Only later, with Urianger's report and Eorzean refugees, did they learn that it was pretty much an actual Calamity.

The memory loss thing seemed to affect mostly only people at Carteneau, and some (apparently) random Eorzeans elsewhere, mostly determined by whether they had plot relevance either in 1.0 or ARR. (Can't be due to Echo shenanigans, given neither Arenvald nor Krile mentioned anything.) Which seems rather limited for the dev-stated case that everyone on the Source got a soul rejoining.

So I'm leaning more and more to the belief that if soul rejoining had any physical or mental effect, it probably was subtle enough to be drowned out by the general panic of "help we're in the middle of a Calamity".

Which brings to mind another question: what happened to the souls of everyone stuck inside Syrcus Tower after the Fourth Calamity?
