At the time, you described that problem as:

I don't have enough information to say why imagemagick or php would be 
broken, as you said it was.

What I do see is that the sclo-php72-php-pecl-imagick has a dependency 
on libMagickCore.so.5()(64bit), which is recorded in the rpm package.? 
If you have a package from a third party repository (either EPEL or 
SCLO, or others), and it depends on one of the few packages in CentOS 
Stream (or CentOS, or RHEL) that aren't guaranteed to be stable, and 
which Red Hat changes, then yum will warn you that the update would 
result in unresolvable dependencies, and it won't upgrade the package.? 
Your system will keep the old imagemagick package and the old 
php-imagick package until the dependencies are resolved in the two 
repositories, and it'll update them after that.

Stream doesn't change that.

On the contrary. Stream will ensure that your systems are perpetual moving
targets so that situations like the one described will keep your blood pressure
high.

Broken packages explained away are still broken packages.
