Here's the first message in the thread that prompted that change:

https://lists.gnu.org/archive/html/bug-bash/2019-03/msg00073.html

It continued into the next month:

https://lists.gnu.org/archive/html/bug-bash/2019-04/msg00007.html

Suffice it to say that there are other considerations: security, using
here documents without any write-mounted file systems, whether or not
using pipes for here-documents can lead to deadlock when using builtins,
and in general whether or not you should write programs that depend on
a particular implementation.
