That's the whole point -- it's continually receiving updates that never break binary compatibility with existing apps/packages. For example, it's a safe target for vendors to target with binary packages, whereas CentOS stream won't be.

That's true of all RHEL major versions. You can safely target RHEL 6 or RHEL 7 without having to worry what minor version they might be running. The same will be true of CentOS Stream which is the upstream for the next minor release of RHEL. CentOS Stream isn't going to suddenly jump major versions.

If the current RHEL release is 7.x then you can think of CentOS Stream as 7.(x+1). You don't have to worry about it suddenly being 8.0. Fedora plays the role of the future RHEL 8.0.
