Perfect thanks, indeed I will be using HPA/Prometheus to achieve this dynamic
consumer addition/removal for better resource consumption, while keeping up
with the production rate of messages (perhaps using the consumer lag property).

Kafka alone wouldn't scale down your consumers, but you can get metrics
from Kafka and use them to change the number of consumers.
Scaling up/down is normally done at other app levels, using tools whose
purpose is to watch metrics and scaling up/down (say HPA kubernetes /
openshift if you are work
