I like the proposal in general but I am against removing lnotab. The reason is that many tools rely on reading this attribute to figure out the Python call stack information. For instance, many sampler profilers read this memory by using ptrace or process_vm_readv and they cannot execute any code on the process under tracing as that would be a security issue. If we remove a 'static' view of that information, it will impact negatively the current set of remote process analysis tools. The proposed new way of retrieving the line number will rely (if we deprecate and remove lnotab) on executing code, making it much more difficult for the ecosystem of profilers and remote process analysis tools to do their job.
