Is there reason to believe that a sensible recursion cutoff (similar to the many SCEV already has) would adversely affect analysis quality in practice? I'd rather avoid the additional complexity if we can.

Recursion itself is rarely the right solution in the first place, let alone working around it by introducing random cut-offs.
