the allow_repeated_speaker function in the selector

What is the doc issue?

Regarding the allow_repeated_speaker function in the selector, I would like to ask why it is disabled by default during the design. Will this avoid any bugs?

Link to the doc page, if applicable

An observation we had before was that a group chat can get stuck if repeated speaker is allowed. It was during GPT-4 days and I think the models have become reasonably good at moving forward on a task. So maybe this is no longer an issue.
