One reason to use something (in spirit) like this is to avoid
unnecessary line changes whenever a new entry is appended to the list,
which might also generate less conflicts. I tend to use $(nil) as the
last item in those cases. The other option is to switch the assignment
to “=+”, but that seems more verbose.

Thanks,
