Impossible to initialize runtime without task migration?

[psznm]

I discovered build option "task-migration", so I thought, I am using each zio runtime only within one thread, without workers. There is nothing to be stolen by anyone. I'll just disable that option.

But I am getting compile error

zig-pkg/zio-0.16.0-xHbVVGNDIwDYoZmY7GkL3RMCKuyc4JjK2hv_4TOBx8x2/src/utils/local_run_queue.zig:212:29: error: steal() is unavailable: this queue was built without task migration / work stealing
            if (!stealable) @compileError("steal() is unavailable: this queue was built without task migration / work stealing");

I made sure that the runWorker is never hit in runtime by using .{ .executors = .exact(1), .thread_pool = .{ .max_threads = 0 } } which results in 0 workers. But I can not compile with .@"task-migration" = false, and the compile error is in place that wouldn't be reached at runtime.

Is what I am trying to do something that should be supported, or am I just trying something that shouldn't be done?
