Some people use VMOS to sandbox apps that require google services, so their main Phone OS stays clean from this garbage.
Also, since Huawei is famously prohibited from using google services on their devices, Huawei users often use VMOS to circumvent this restriction for selected apps that wont work without GMS.
Add an alarm to play VERY LOUD if the button is not pressed in a 5-7 minute window to keep you working. If you fail to do so the entire office/house has to hear your alarm going off
