Right. We should never create $XDG_CONFIG_HOME/emacs.

By 'this part' do you mean the XDG_CONFIG_HOME related changes, or
also the suggested change to prefer ~/.emacs.d/init.el when no config
files exist? The latter is a relatively small change, but itʼs in a
convoluted area of startup [1], so Iʼd have no problem with leaving it
alone.

Footnotes:
[1]  I made the change, tested it, and it gave incorrect results, so had
     to re-do it. Twice.
