Good question. I would prefer to wait until 5.7 gets release or even
longer. Changes in console registration order are prone to
regressions. People then complain that they do not longer see console
after reboot.

linux-next and rc phase has only pretty limited number of users.
Released kernels hit much bigger user base, for example, via
OpenSUSE Tumbleweed.
