No, we don't want that. I find Slack to be slow, clumsy, and inefficient. Monolithic services like Slack don't provide the flexibility of federated services like email.
I use a desktop mail client. It's faster, has more powerful search features, works with any email service, I don't need to pay anyone a fee to access my old mail, and I can use it even when I'm offline.
