Yes, but people in business tend to get a lot of emails, and if most of them resort to text summarization then the nuance is lost anyway. And it's mostly lost if the recipient skims.

Also, many senders of email aren't necessarily great communicators conveying valuable nuance anyway.

Ultimately, it's a cost-benefit calculation: get occasionally-valuable nuance on a bunch of emails, or keep emails simple and do something else that might be more valuable?
