However you could fake it, by including backslashes in the delimiter,
which would allow literal newlines, but bash would ignore them as they
are escape sequences. So they wouldn't actually be a part of the
delimiter from bash's perspective, but merely visually and accepted
from the literal input.

$ cat <<EOT\
$ EOF
$ hello
$ goodbye
$ EOT\
$ EOF
hello
goodbye
$
