Is this something user typically want to use a single setting,
or would it often be per invocation?  Especially with the new
invoker in send-email, wouldn't it become more like "if I use
imap-send to stuff things in my outgoing folder, they shouldn't be
marked as read, but fcc copies send-email stuffs via imap-send
should be marked as read" or something like that?

If we never marked these messages as read, then this default is a
breaking change, isn't it?

IOW, this smells problematic.

Why so many braces around single-statement blocks?

According to

https://github.com/curl/curl/blob/master/docs/libcurl/symbols-in-versions

CURLULFLAG_SEEN first appeared in 8.13.0; INSTALL says we require 7.61.0
or later, so this may be OK.
