For workstations and servers there's still hundreds of low priority housekeeping threads that can run on efficiency cores. Using them means the work gets done for less power and thus less heat. While a server isn't worried about battery life every saved bit of power is saved dollars in aggregate in a data center.

It also avoids scheduling conflict between housekeeping / background tasks and "user" stuff, which means more predictable and stable throughput and better cache utilisation (your cache doesn't get blown because the system needed some time to zero memory or update something).
