No, that's not what CWG asked.

CWG asked to map all line-terminators to Unicode new-line in phase 1,
and define lexer new-line as exactly Unicode new-line, and then revert
all grammar changes introducing line-break for new-line.

Also, the paper was lacking phase 1 changes synchronized with the
current working draft.

The were musings about somehow conflating or concatenating multiple
whitespaces, but that didn't achieve consensus.
