Exactly. I was wishing for an AWS based cli accessible credstore service for a while and didn't even know this existed until just the other week.
One big problem with AWS and their incremental features / improvements is you never hear about much of it, or its buried in a post from Jeff's blog that you have to watch like a hawk to keep up with.
I can recommend subscribing to Most recent announcements from AWS[1] for keeping up. You'll get weekly summary emails with headlines, HN style. They link to articles here[2].
Since a while, I subscribed to „AWS this week“ on YouTube from a cloud Guru. This is just 5 minutes, and you have a good idea what‘s going on. (I have no affiliation)
