This is a nice feature to have for those who tend to have back to back meetings and may not even get lunch break.
Just a note that, this is not a new feature. While the ability to set scheduling defaults that would automatically shorten meetings was made available to end users back in July 2020, this release gives the admins to set default values to everyone in the organization, with options to end early, start late or none at all. Check it out and you may want to implement this and provide that well deserved breathing space for your colleagues.
