I'm the guy who dropped the ball on that series.  I still intend to pick it
up (honest!) but I just haven't had the time.

The impetus was originally getting relative submodule paths to work on
detached HEADs [1].  My patch for that doesn't work when someone does "clone
-o", because various parts of git assume there's a remote named "origin".
The discussion led to the idea of using the remote name specified during the
initial clone, and implementing that as a remote.default config value.

As for why "clone -o" exists, it was added in v1.1.0:

    git-clone: Support changing the origin branch with -o

    Earlier, git-clone stored upstream's master in the branch named 'origin',
    possibly overwriting an existing such branch.

    Now you can change it by calling git-clone with '-o <other_name>'.

    [jc: added ref format check, subdirectory safety, documentation
     and usage string.]

It sounds like the original need for the -o option is no longer pertinent.
OTOH, for folks who deal with several remotes it's nice to name them, and
"origin" isn't necessarily a useful or intuitive name.

                M.
