I am using the same criteria I have always used. If you would like it
changed, we need to discuss it at a macro level, not for individual
cases where we feel someone didn't get enough _credit_.

And, I will restate this again, the release note are not for _us_, or
for _credit_ --- they are for our general users. If you would like that
changed, you need to make a case for that change.
