| However you could fake it, by including backslashes in the delimiter,

bash does, so does mksh, zsh, and bosh, most other shells don't. Just
another annoying incompatibility.
(line joining using \ isn't technically an escape sequence, but that
detail is irrelevant here).
POSIX says:
It is unspecified whether the line containing the trailing delimiter
is itself subject to this line continuation.
which means that nothing is required to make that work. Further, unless
bash documents it as working, it is free to change the way it works for
that at any time, so was anyone to take your advice and actually use that
method, then they'd be risking their code breaking in a subsequent release,
with perhaps no warning at all.
