Thank you for your feedback! The team is planning for this work. We will share an update as soon as one is available.
For the separate feature ask to disable attendee audio, we are pleased to announce this has been released. For more information, please see this UserVoice item https://microsoftteams.uservoice.com/forums/555103/suggestions/39784519.

Agreed - attendees should not be able to unmute themselves if a host/organizer or presenter muted them. Also not to mention Live Events is VERY clumsy to use - nowhere near as easy as WebEx Events or Zoom, and the latter having that is sad
