I thought so, but I installed Sleep Aid, and when I disable "Wake for Maintenance", Sleep Aid gives me a stern warning:

> Disabling "Wake for Maintenance" can lead to this Mac waking every few seconds. Please select "Disable Wi-Fi" to help with this

So it seems like actually Enabling this setting somehow prevents the Macbook from waking up every few seconds... presumably due to Wi-Fi? Enabling it seems like the recommendation by Sleep Aid anyway
