There seems to be interest in solving this issue. I strongly suggest
those interested should get involved.  I have opened a defect to track
the issue to keep Centos7 in the AB.

https://bugzilla.yoctoproject.org/show_bug.cgi?id=13714

The YP TSC is putting a time limit  of  1/20/2020 (3.1-M2) when we will
revisit this topic and determine where we go from there.

Kind regards,
