Missing warning casting integer pointer -> capability pointer in hybrid?

[acoplan-arm]

I noticed that CHERI-LLVM no longer seems to be warning about casting integer pointers to capability pointers in hybrid. E.g.:

int * __capability f(int *p)
{
    return (int * __capability)p;
}

doesn't seem to provoke any diagnostic. Conversely, a cast in the other direction provokes an error suggesting use of __cheri_fromcap (as expected). I seem to remember that CHERI LLVM used to warn on this (and suggested use of __cheri_tocap). Did this get dropped intentionally, or am I misremembering?
