Fedora's @mattdm says give CentOS Stream a chance https://lists.centos.org/pipermail/centos-devel/2020-December/075503.html
Regarding CentOS Stream and 'enterprise' Linux, I think five years is an appropriate period of support. The two-year cadence for Debian really works for me. Six months is too short. Maybe one year would work.
It looks like CentOS Stream releases will get five years of support https://centos.org/distro-faq/#q6-will-there-be-separateparallelsimultaneous-streams-for-8-9-10-etc
