Not really. Black-Scholes (and its variants) tend to assume log-normal rates distributions. But that’s just a default, and one chosen with the explicit assumption of positive rates.
Most practitioners have had custom curves for decades; using one that pierces zero is a trivial modification.
Is there any answer to it yet ?
