> 2) the standup's facilitator now stops devs from going into too much detail, "you guys can discuss it further after the standup"
I said this in another comment, but a standup I'm part of tables these until the end of the call; and then anyone not involved in that conversation can drop off. It seems like a reasonable compromise to balance the need to get people together to discuss something against the need to not keep people tied up. It helps mitigate the issue of people not wanting to plan a meeting to just "talk about" something (when that's actually what is needed).
