Subject: wscons: "ESC in kernel output" triggers a panic?

Some testing code of mine recently tripped over this bit of code in
wsemul_vt100.c: 

            case ASCII_ESC:
#ifdef DIAGNOSTIC
                if (kernel)
                        panic("ESC in kernel output");
#endif


I'm puzzled. What is this good for? Why is printing an escape sequence
from the kernel forbidden, and in such a drastic way?
