You find it acceptable in most other programs. What problem are we
trying to solve with this overflow checking? We should do something
about unbound recursion in Lisp, but in C? Why? We expect a much higher
level of robustness in the C code.
Besides, we already crash if we overflow the stack while we're GCing.

Yes, and the proper response to stack overflow in C code should be to
crash. We shouldn't be allocating stack without bound in C.
