I guess resource allocation would be under utilized, but being able to respond to web requests allows for a single lambda to execute for any number of different requests. For example we had a client who wanted a SOAP service to interface with our system, so instead of creating a WCF service or something and hosting it in IIS, we used SoapCore which is just middleware for accepting a soap action or sending the wsdl information back. So we have a small lambda (it's like 500kb) in a Lambda accepting ~1-10 requests during monday-friday for this client. And since Lambda only charges for duration of execution time it ends up costing nothing as it falls into the free tier. So even if the resources are underutilized I don't see an issue.
