A command line option is cumbersome that you have to type it every
time, so configuration variable makes 100% more sense than an option
to "git merge".  

If your merge used the merge (as opposed to diff3) style, and seeing
that the resulting conflict is not easy to review and you wish you
used diff3 style instead, it is way too late for any option to "git
merge" to help you.

But having an option to "git checkout" lets you move forward from
that state, so it also makes 100% more sense than an option to "git
merge".

So, it is not odd at all.  Just compare between merge and diff3,
think which one would often help you, configure to use it by default,
*and* at a rare occasion where the chosen default does not work for
you, let "checkout" help you.  The thing is, unless you first attempt
to "git merge", you won't know what shape of conflict you would get,
so you cannot choose the right conflict style command line option,
even if one were available.
