Our landlord proactively offered! We pushed back a little and got an overall savings of around $6000 for committing to another year in an apartment we love. Well worth it.
Added bonus: The apartment is rent controlled so it will take 2 to 3 years before rent climbs back up to our old level, if we stay.
I'm not sure rent control works that way. I think it only depends on the base rent, which is the rent in the year you moved in. I don't think later reductions reduce the base rent.
Which implies if you want to lock in lower rent with respect to rent control, you have to start a new lease in a different location.
