I like it! I've been doing something similar to make it super easy to switch between projects / profiles by never having a default one set and using named profiles only. That seems to have avoided a few footgun instances.
Not having a default profile in ~/.aws/config is a good idea.
Additionally, you can use direnv to set your environment vars for a specific directory.
I use
cat ~/.aws/config | grep "\[profile" | sed 's/\[profile \([a-zA-Z0-9_-]*\)\]/\1/'
to get the profiles for auto-completion. Might be faster than the CLI command.
I like it, but aws configure list-profiles handles profiles that are set only in ~/.aws/credentials (I know people who have this), plus when either file is missing, plus if AWS_CONFIG_FILE or AWS_SHARED_CREDENTIALS_FILE point to different locations.
Sure it is the more general approach. I think you should use your version if you want to be compatible to different users. If you have full control of your own setup my approach might be faster but has some assumptions.
have you considered: https://awsu.me/
Lots of people like AWSume and other tools like it, but I tend to prefer to go as lightweight as possible around AWS-produced tools, because I want to know how those tools can be improved. For all the good AWSume does, it also means people don't ask AWS to make the underlying product better. I don't want AWSume to be necessary!
export -nis needed because of this AWS CLI issue aws/aws-cli#5016
