Who will bring it up? I've never worked at a company where managers are suddenly assholes who diligently apply unreasonable policies. My experience is committees make all sorts of policies, but unless consequences are doled out by some automated system, no on actually cares or follows the policy.
At my current company, there's a place I think I can see my reports' office attendance, but I've never actually checked it. Why would I? I'm not even a WFH zealot myself; I just don't see why I should care if they're in the office.
The managers will bring it up because they have pressure on them coming from higher up to have their reports all be compliant with the work-from-office policy, and in extreme cases, they would be expected to manage out the people who are flouting it. Not doing these things could easily result in an unsatisfactory performance rating for the manager.
