I haven't been able to find concrete stories either, though these[1] statistics might be an indication. It shows there's a few EVs per year that lead to a building fire, though sadly nothing further about source. So could be something else like battery.
That said there's been a campaign for several years trying to get rid of sockets for high current or permanent installations. I recently replaced both an electric water heater and mini split AC, and in both cases the previous appliance had used a socket and that was not allowed anymore.
In most of Europe high current would be 32A, 16A is generally the standard (though I know Switzerland uses 10A and I believe UK plugs are rated for 13).

Could well be they're just being proactive.
