the following make perfect sense and come from the first page of google
hits.

Google is not always your friend. Some links are totally irrelevant. All
other concerns are addressed by changes in the 2008 NEC.

Maybe if you read and understood the links....

But your ignorance is bliss.

Audiophiles just abhor them!

Your link does not support that.

And audiophiles also like gold plated speaker wire.

The change in the 2008 NEC requires breakers "simultaneously disconnect"
which addressees any problem in this link.
And a competent electrician will verify all wires in an enclosure are
dead. This is rather easily done with a "non-contact" voltage indicator.

Suggests using a breaker that disconnects all wires. As above, that is
required starting in the 2008 NEC. In some cases it was required before
that.

Totally irrelevant - nothing on "Edison circuits".
Talks about "Edison base" fuses and circuit breakers that screw into
those fuseholders.

Also totally irrelevant. (But does include the phrase "Edison Circuit".)

Repeat of the irrelevant link above.

Just continued delusions about multiwire branch circuits (Edison circuits).

Maybe you could write a code change proposal. I am sure it would get the
appropriate consideration.
