The fact that I have to spend more than 5 seconds considering how to integrate my Red Hat Subscription into my test builds (for dozens of projects) means I won't do it.
That's why I stuck with Rocky Linux instead of just dropping all RHEL support entirely.
And there are _a lot_ of test runs where I have more than 20-30 test containers running simultaneously with Rocky Linux 8 and 9.
Do I have to write new software that limits my test infrastructure to only run 16 tests at a time or something idiotic like that? Do I have to even wonder about that using Debian, Arch, heck even Amazon Linux? No.
