That's a good thing, but still not enough. For starters, if I edit
.git/config, next time autogen.sh is run it will revert the edits,
right? The script I use for building Emacs contains

git clean -f -d -x
./autogen.sh

... to ensure that the build is not tainted by previous builds.

How about mentioning (not applying) the recommended settings on
autogen.sh, with instructions for running a script that makes the
changes? That ensures that the user is aware of the changes, and agrees
with them.

How those settings benefit Emacs development? (In contrast to any other
project that uses git.) I asked that on my first message, but there is no
answer yet.

Okay, you explained why Emacs checks that UTF-8 is used on the commit
messages of their repo (I thought that git records the text encoding and
then converts it before display; that's basic functionality for a
distributed VCS, but if you say that an explicit setting is required for
avoiding making a mess of the VC history, I believe you.)

Now, what about the reasoning for the recent changes, in the context of
Emacs development? (Other than "they look like a good thing to me, so I
will put them on everyone's repo.")
