Happily my current team contains remote workers, so even before covid, 'standup' consisted of at least two rooms of people staring at a screen or conference room phone. I haven't had to stand for five or six years.

Also the flip side of the "some people can't do thirty minutes" is "some people could do six hours". Trying to use gravity as a timer does not work on endurance athletes at all. And they often have partial immunity to long, drawn-out activities. An alternative mechanism to control for time would be less problematic all around.
