I’d love to see companies convert ‘Unlimited vacation time at your discretion’ over to ‘Unlimited remote at your discretion’.
"Unlimited vacation" is a deception. Real perks are to have 15 or 20 days of vacations, increasing with seniority at the company, and forced vacations (i.e., the company forces you to take the vacations every year). It is also good for the company health (ensure that no 1 person missing has a large impact).
Believe it or not, many people for many years had to come up with some sort of excuse to work remote (have to pick up the kids, waiting for plumber/delivery, etc), so normalizing remote, even nominally, would be a good step forward.
Of course a global pandemic helps move the agenda too.
