We use a custom verbose log level in pmbootstrap, unfortunately it isn't possible to correctly type this due to some limitations in the logging library [1], [2]. Given that our usecase is fairly simple, we can just wrap the module with our own so we only have to tell mypy to ignore the error once instead of at every callsite.
