Review comment:
@devaraj-kavali @vanzin
While resolving merge conflict in #23260, I found two observations here:
1. What output we expect when `env` have more than one matching keys? This
looks like always leveraging the last key which is indeterministic if there're
more than one keys being matched.
2. here the `user` is not a `value` but a `(key, value)` here, so we need to
use either key or value (I guess we would like to pick `value`).
