Rancher and Harvester Support Matrix Problem

I checked the support matrix and found that Rancher v2.7.15 is compatible with Harvester v1.3.2.

However, Rancher v2.7.15 supports downstream clusters is 1.23 to 1.27, while in Harvester v1.3.2 rke2 is v1.28.12+rke2r1.

I am puzzled about this. Will there be any problems if used in this way for a long time?
