Forcing introverts to get out of the comfort zone and talk to each other has lots of benefits. Async Slack gives everyone the opportunity to tune out, which they definitely will. A blocker can be resolved either on the standup or during a quick follow-up call that happens right after. Going async risks that the same blocker will be resolved in 1-2 days. I strongly recommend against it.
