One of Rob's questions on V(N-1) that seems to have been ignored/only
partly implemented:

You did drop the -v2.1 that he requested from the SoC compatible, but I
amn't sure why the above was not implemented (at least there's no
explanation in the previous thread's version, nor in the changelog
here...)
