Very few insurers will insure literally anything (back in the day, Lloyds of London were notably unusual in that they would write a policy on basically anything, though you mightn't like the cost). Most conventional insurers will have a line after which they say "this is too risky, we'll leave it to specialist insurers". Ask anyone who's ever tried to get insurance on a non-conventional-construction house.

And it's a pretty niche vehicle; if they do find it unacceptably risky, then dropping it is presumably a fairly easy decision.
