I tried signing up to the CI mailing list and it immediately became
overwhelming.
Also the CI UI could use some improvements.  I'm pretty sure I've
mentioned this before, but there is no easy way to find out which inputs
I need to fix to make a dependency failure disappear.  I think everyone
has better things to do than perform a linear search by hand.
So I rely on my own installations for detecting errors, that way I at
least know that I don't get flooded with notifications for packages I
know nothing about.
One possible improvement I have been thinking about is making it easy
for users to filter CI output to the packages in their profile closure,
so for example they would get advance notice of any broken packages
*before* attempting to install them.
Teams could also have their own filters.
