I use to have a neighbor with a car that made all nearby buildings shake, 5am every morning, idling for 3-4 minutes. It always made me laugh but it never struck me as beautiful.
EVs are required to produce sound for pedestrian safety, but they are absolutely beginning to make faked IC engine sounds for aesthetic appeal. See the Ioniq 5 and Dodge Charger EV.
If it's required, then you can differentiate your product on the market, but the regulatory requirements are driving the decision to spend money on it.
