I think the changes you propose should be done in a separate policy proposal as they are an addition to this policy proposal rather than a change.

I agree with Matthias here. Since 2023-01 does not introduce the
language Nick points to I find it unreasonable to demand that this
proposal should also fix any issues in that language (if they are
indeed in need of fixing). This proposal aims to solve a different
problem, after all, so fixing other issues is not in scope.

I see no surprises in the Impact Analysis, so I reiterate my support
for moving 2023-01 forward.
