1. draft-faltstrom-unicode12 have two main issues:

1.1. It does not address Unicode 12.1 (easy fix)

1.2. It suggests a resolution to the divergence between Unicode and IETF due to incompatible changes in Unicode that makes IETF follow the Unicode Standard by allowing derived property values to change (better to let 5892 rules be fixed).

2. draft-klensin-idna-unicode-review do suggest the derived property value stay fixed, which implies 5892 algorithm must be updated in the case Unicode do changes in the future like has happened before as described in draft-faltstrom-unicode12.

Because [1.2] and [2] above are incompatible with each other, text in them should and I would say MUST match each other.

What we have as a fact is that IETF have already accepted actions based on draft-faltstrom-unicode12 until Unicode 12.0 at least so applying draft-klensin-idna-unicode-review to the review process can not happen for earlier versions.
