Can you contribute to this optimization?
If you plan to contribute to this optimization, because k8s tasks cannot support underscores, you need to add a tooltips to prompt the user when creating tasks. In all k8s modes, underscores will be replaced to avoid inconsistent task names resulting in a series of FAQs.
