I think some (but certainly not all) in-the-office people only realize their desired context if everyone else is there to populate the office and give them easy access to co-workers. For some (not all): what's the point of being in the office if it has few of the people they need to interact with?

If a dev isn't performing well go through the PIP protocol and then fire them. If a dev IS performing well but you're afraid they might be working two jobs is it really a problem (and if so, why)? This is the sort of thing that'll shake itself out over time and feels like fear mongering more than anything. People screwed around in the office and took way too long to do things too, they just had to be sneakier.
