This is the part that concerns me as well. WFH was a fluke of sorts and the timing allowed a lot of workforce to maintain rather adamant pose. My company's management is already using all the 'key' words in meetings like 'in person collaboration' and so on suggesting they are planning an RTO.

They just don't seem to dare to do it yet, because they poached a whole lot of people from companies that did RTO. This would like leave a bad impression.
