Ehh, what exactly did you write ;-)?
I think the most important thing that needs to be explained by the
log message for this change is that the variable is honored only by
log and it needs to explain why other Porcelain commands in the same
"log" family, like "whatchanged", should ignore the variable.
I think that we must not to allow format-patch and show to be
affected by this variable, because it is silly if log.merges=only
broke format-patch output or made "git show" silent. But I didn't
think about others. Whoever is doing this change needs to explain
in the log message the reason why it was decided that only "git log"
should pay attention to it.

The variable name may want to be updated to mimic other variables
used in a similar way, e.g. default_show_root is used to store the
value from log.showroot.
Perhaps "default_show_merge" or something?
Thanks.
