Conversely, sometimes when you have 23 people designing something, they can lose track of what they’re trying to accomplish and focus on how they’re trying to accomplish it. It can be an XY problem sort of thing. “How can we get the Redis queue to do an exactly-once insertion into Kafka, if we can’t guarantee exact ordering from the Paxos framework?” “Uh, guys, aren’t we trying to send out the weekly email newsletter to our estimated 500 subscribers?” “Oh, well, I guess we could just use Mailchimp…”

Like I said earlier, it’s ok not to believe me. I don’t particularly mind. But just between us, my solution met every one of the project requirements using COTS parts because they’d made it waaayyyy harder than it needed to me.
