Mimir is just architected for a totally different order of magnitude of metrics. At that scale, yeah, Kafka is actually necessary. There are no other open-source solutions offering the same scalability, period.
That's besides the point that most customers will never need that level of scale. If you're not running Mimir on a dedicated Kubernetes cluster (or at least a dedicated-to-Grafana / observability cluster) then it's probably over-engineered for your use-case. Just use Prometheus.
