I suspect that the use of external-body has been almost wholly, if not
completely, supplanted. Of MUAs, I think that at least mh supports the
functionality, but is anyone using it?
I use mh, but I don't use message/external-body. It's not that the feature
is a bad idea, it's that mh's user interface for it is too annoying to use.
I'd like to know what could be done to encourage other UAs to implement it,
and in a user-friendly manner. (no, using HTML tags doesn't provide the
same functionality)
