it would be nice to have dev-db/mongodb arm64 keyworded. mail-mta/postfix which is arm64 keyworded has an optional dependency on mongo-c-driver which has a dependency on dev-db/mongodb. We get around it by stable masking test USE flag for mongo-c-driver for arm64 but getting rid of that mask is probably a better option if we can get mongodb stable arm64 keyworded. thank you
