Don't special fares apply between Kenton and Harrow & Wealdstone, on
the Bakerloo Line? What's that about?

I think you are confused. I have been to Harrow & Wealdstone without
needing to pay a special fare. "Watford Junction (special fares
apply)" is in

ISTR stations north of H&W became part of the LU ticketing system when
London Overground took over that line. Trains only take 7 minutes
between Watford High Street in zone 8 and Watford Junction.

The mainline (LM and SN) trains only take that long between H&W and
Watford Junction.
