I think that is a planned observation. Perhaps underway in this dimming event.
As for a large body near the stars Roche limit, that object would be in a very short time period orbit, and while we might discern changes over several cycles, successive events would be highly similar.
We aren't seeing anything like that.
Also, the proffered comet cloud theory seems to me to be very weak, why this one star has something like that (that I still don't think would produce the lightcurve seen, BTW) and no other star has something same/similar is a real poser.

The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.
