It might work well for you, but are you sure your recipients aren't seeing emails that look like this? Sending plain text emails that look good when nearly every email client is mostly only tested with html emails is actually very difficult, and sometimes simply impossible. Format=Flowed doesn't always fix this. Plain text emails are defacto deprecated just because a lot very popular email clients don't handle them well. One major problem with plain text emails is the standard was created when nearly everyone had a screen wide enough to display at least 78 characters per line (or whatever it was). Today people spend most of their time on screens much narrower than that. FF is a half assed solution to that problem html was designed to work on a much wider variety of screen sizes so it works much better for email. I say this as an offlineimap/mu4e user who knows some of my recipients are seeing bad formatting and doesn't really care.
