In Germany we have a slow dying of mall and similar, now accelerated because of corona. I have considered this before when seeing some empty buildings (turned out they just moved...). One thing I see as a problem is sunlight. Any apartment must have reasonable sources of natural sun light and many mall's are build in ways which have much less entries for sunlight. Outer walls can be changed but the "inner space" which has no contact to an outer wall is stuck.
