Even if you wanted to you might be able to update Entity data but you will miss all the instance
data and hence lineage will become inconsistent.

That is the case for bootstrapping too, the user cannot get any historical instance data.
If the user toggles the feature, it should be made clear to him that instance data during
the time the feature was turned off will not be available. If we expect them to clear the
DB, then, we should call it out and also tell them how to do it.
