"handle the case" is way underspecified.
Until I peeked the patch, I couldn't tell if you were now allowing
"git remote rm" that does not say which remote to remove the remote
named via remote.default by default, and had to wonder if you made
"git remote rename frotz" without any other argument mean "git
remote rename <remote.default> frotz" or the other way around.
The "rename" and "rm" commands adjusts the value of the
remote.default variable when they make the current default
remote disappear.

Probably sensible, but I could easily imagine existing users to be
surprised, harmed and complain, especially now those who want this
behaviour already have a separate "remote default" command to set it
themselves.

Avoid cute and not-widely-used abbreviation; in other words s/<remo>/<remote>/.

I would like to see people think, when their "new feature" breaks
existing tests and needs adjustments, like this:
Even test scripts gets upset with this unexpected behaviour
change---real users may also be hurt the same way. Should we
really need to do this change? What can we do to help them?
Even though I said "Probably sensible", I would prefer the "first
remote automatically replaces 'origin'" feature not to be part of
this patch. It is something we can queue separately on top as a
separate feature.
I personally think in the long run it is probably the right thing to
do, but at the same time, I do not think it is something we want to
throw at the users as a flag-day event without transition planning.

After saying something long-winded and convoluted that you think it
needs "In other words," appended, try to re-read the sentence
without the long-winded part (and "In other words,"). I often find
that the long description is unnecessary after doing so myself.
I wonder if it makes the result easier to read if you consolidated
all the duplicated explanations of what the "default remote" is/does
in this patch and previous patches to a single place (perhaps
glossary) and refer to it from these places, e.g.
default::
Display or sets the name of the default remote for
the repository. See "default remote" in
linkgit:gitglossary[7].

This is unrelated to your patch, but I wonder what should happen to
this repository:
git config branch.foo.remote origin
git remote rename origin upstream
Should branch.foo.remote be updated, and if so how (either set to
upstream or configuration removed)?

I think your patch actually removes remote.default (which I think is
good), and describing it as "changes default remot to 'origin'" like
you did above is perfectly good.

Perhaps it is a good time to update the naming convention of

Good. If somebody anal cares about the vanilla hardcoded default
'origin' and 'remote.default' having 'origin' as a configured value,
he should be using "git config" to ask the difference. Users of
"remote default" interface should not have to care.

I am not sure if this is a good idea. Shouldn't "git remote default
frotz" followed by "git remote add frotz" work? I'd prefer to see
this demoted to a warning, perhaps like this:
if (!remote_is_configured(name))
warning(_("No remote named '%s' defined yet."),
name);
git_confg_set("remote.default", name);
without the noisy report of "I did what you told me to do".
