While it sounds a good idea, I feel the take up would be low as tyron bands (which do a similar job) are not that widely fitted.

I was under the impression that blowouts are less servere with newer wheels as the tyre should not leave the rim fully any more.

Most blowouts are preceeded by either higher tyre temperatures and/or lower pressures.  To my mind a pressure combined with temperature sensor used without the run flats would solve 99.9% of blowout issues.

PS If you are concerned Land Rover offer a 6 x tyre pressure set combined with a reversing camera set that can be retro fitted to most cars, not just Land Rover models.  The system is quite neat as it all combines in an Electrochromatic mirror so no screens or displays are on show on the dashboard.

Run-flats may be too "solid" in the side-walls for caravans, therefore reducing the "suspension".

Caravan tyres which are commercial vehicle tyres mostly have re-enforced sidewalls already so are much stiffer than normal tyres.

A run flat system would have to be incorporated into the tow car on manufacture for anyone to want it,retro fitting all the sensors and wiring for the instruments would put most people off.

I agree perhaps a temperature sensor which would be easier to fit would give some warning that something is wrong

In a country where caravans are not even subject to an mot test or proper registration, I would guess there would be little interest in this.
