Often times a single person in a group working remote can cause problems. It's only when the entire team is remote at the same time, either entirely or partially on the same days, does remote stop becoming a concern in the ways you mention.

Teams tend to do better when they're sharing remote or sharing coming in. Teams tend to do the best (ymmv) when they're full remote but are local, so they can come in as much as they want to meetup when it is beneficial to do so.
