My opinion is quite the opposite.

With a small program, it's rarely difficult to work out what's going on. If your small program develops a performance problem, it's usually fairly tractable to work out what's going on, and modify it. In extremis, you can just rewrite the whole thing.

Large programs are another matter. Hidden control flows in C++ (for example) can make pinning down performance problems extremely difficult. And then widespread refactoring can be extremely challenging.

Zig forces everything to be an explicit interface, which should make maintenance work on large programs much more tractable.
