It was discussed to err on this rather than leaving it empty. My main concern would be that someone would want to set this to something on their shell, like export AWS_EC2_INSTANCE_PROFILE_NAME=$(some_process_that_returns_a_value), and that something returns an empty string, then they would make a request to the base URL rather than to the profile they were trying to use

This was addressed but not here -- it actually uses Lookupenv to check for explicit empty in the main load routine.
