Add function to ban sender IP in submission operations menu

It seems this would be better as starting in contributed module but I am not sure. There exists a module that does so → in some way. Perhaps it could get a stable release and be integrated with the core ban feature.

Perhaps a Webform plugin since it has gone the way of pluggable options. But since there is a contributed module, maybe that will suffice. Hopefully, the maintainer of Webform Ban → will get the security issues sorted soon. Thanks for sharing that as an option.

Yep, this feature should be handled via a dedicated contribs module.
