But nothing in this tread points even REMOTELY to K&T wiring. It was

all "ungrounded romex"

To be fair, if accessable, you could make a good argument for replacing that as well, because any ungrounded non-metallic cable likely does not have a 90C temperature rating as does currently produced NM-B.

If I saw any K&T I'd be tempted to draw up a plan for eventual complete replacement ASAP however... even if it was done perfectly when installed simple age makes one worry about the integrity of the insulation... nothing lasts forever.
