The criticism of a Dyson shell that I have read is (as you suggest)
that the civ would have already mastered nanotech, fusion energy, etc.
so that they would not need to use the sun energy. So they would have
better things to do with their resources than building an enormous
Dyson shell.

There are probably several things going on with this peculiar star,
that cause the radiation to vary.
