Oops, I had indeed missed that important part of the discussion,
you're completely right.

However note that the file pointed to by the BASH_ENV
environment variable is sourced even by non-interactive shells
(as long as bash is not called as "sh" or with --posix or with
POSIXLY_CORRECT or SHELLOPTS=posix in its environment)
So, putting function definitions in /some/file will make those
function available to all non-posix bash instances that receive
BASH_ENV=/some/file in their environment.

Now, I'd agree with you you probably don't want to do that, and
the most sensible thing is to source your shell function library
file from your script.
