Why do you think its bad? From a secruity standpoint its obviously not great, but its undeniably more convenient than running a curl command to pull in a third party .repo file, yum update and yum install to get something that isnt easily available in my base repos.

Im not sure the software center being half baked is even the real problem.

One of the nice things about Windows is that you dont need a central, curated, repository for software. You can google the thing you want and just download an msi/exe of the latest stable version and, 99.9% of the time, leading back to your first point, it will just work.
