So with power FETs
rated to 800 volts and staggering amounts of amps being readily available
almost for pence, why would anyone actually design with IGBTs ?

The main reason is that they're considerably cheaper when you need
both high voltage rating _and_ high current rating. That's because
they use less silicon die area. On consumer products the cheapest
component that will do the job acceptably well usually gets designed
in. Try pricing a 30A 800V MOSFET vs. a similar rating in a IGBT.. the
MOSFET will probably be 5x the price.
