I don't think there's a fundamental reason they cannot be mixed. In
fact, you can do what you want with:
git -c clone.defaultRemoteName=foo clone ...
(which, btw, might give a better solution than remembering to use "-o"
each time, since you can put that in your global git config).
So we are just complaining about the actual "-o" option. The conditional
which catches that comes from 8434c2f1af (Build in clone, 2008-04-27),
which is not much help. Before that, the same logic was in the shell
version, which was added in Junio's e6489a1bdf (clone: do not accept
more than one -o option., 2006-01-22), but there's no explanation given.
I do think the remote name is less important in a bare clone, because we
don't create refs/remotes/foo/* there. But you might still care about
the name of the remote for doing "git fetch foo", etc. So I imagine we
could simply loosen the check like:

This second case is IMHO a minor bug in the git-remote code. As
documented in git-clone(1):
--bare::
[...]
Also the branch heads at the remote are copied directly
to corresponding local branch heads, without mapping
them to `refs/remotes/origin/`. When this option is
used, neither remote-tracking branches nor the related
configuration variables are created.
So it is expected that there is no configured refspec in a bare
repository. But it looks like the remote-renaming code is not prepared
to handle this case. The backtrace for the error is:
#0 die (err=0x5555558c349a "could not unset '%s'") at usage.c:175
#1 0x00005555556bce85 in git_config_set_multivar_in_file (config_filename=0x5555559bc700 "config",

So probably it needs to use the "gently" version of git_config_set_multivar(),
which avoids calling die(), and then check for a return code which
indicates no value was found.
