Here it is, after #30073 discussions: I got back the kind of banner that appeared previously, only aligning skip-links to the left.
As a bonus (feel free to discuss it, of course), I enhanced progressively the whole thing by making all skip links appear together when :focus is within the container.
And to stay consistent with #30866 I used utilities, seems legit in that case.
