Having now worked in one of these at a large company, we found those sorts of "team offices" hurt collaboration and innovation even more than open floor plans. Unless the company is relativley small, the random conversations between people from different teams is often the key to innovation and getting problems solved early without having having to have formal meetings and delays. A team room means that to ask a co-worker on another team a simple question (or to just see what they are working on) becomes a big deal because you are now entering that other team's space and interrupting a dozen people. Unless you really know the other person well, we found people just are very hesitant to do it.
In big companies, there usually isn't a problem with communicating within a team - the problems occur when teams aren't communicating with people in other teams. These team rooms ruin informal inter-team collaboration and communication.
With the pandemic it isn't hard to see that a small enclosed team room with people packed in it is also a pretty good way to guarantee a virus will be spread to others.
