Although we could say the same thing about Kafka, couldn't we? It's made for much higher throughput and has usually other use cases, but it's also great until it's not great.
At least the last time I used Kafka (which was several years ago so things might have changed) it wasn't at all easy to get started. It was a downright asshole in fact. If you pursue a relationship with an asshole, you shouldn't be surprised when they become cold to you
