I think the answer to that question depends entirely on the employer. While some are making waves becoming remote companies, the vast majority are chomping at the bit to get butts in seats. I know several people who have been called back in, to sit in an enclosed office in their cubicle for 8 hours a day with their mask on doing the same exact task that could be accomplished on their laptop at home.

Why? No reason at all beyond managers wanting to see people physically in the office working. The management class rarely takes a page from science and reason when making decisions, gut feelings are king, and the gut feeling in many boardrooms right now is that people are slacking off working from home. Whether that is true or not in real world productivity isn't considered. That's why I think not much will change ultimately once things do eventually return to normal, whenever that may be. People will go right back to living conveniently to work.
