Zero-address checks are a best-practice for input validation of critical address parameters. While the codebase applies this to most addresses in setters, there are many places where this is missing in constructors and setters. Accidental use of zero-addresses may result in exceptions, burn fees/tokens or force redeployment of contracts.
Recommend adding zero-address checks.
