U+0130 is disallowed, however most implementations do mapping for lookup, in which case U+0130 changes to U+0069 + U+0307, due to the application of NFKC + Casefolding.  http://www.unicode.org/Public/idna/8.0.0/IdnaMappingTable.txt 

Or is lucid only concerned with the case where no mapping is applied?

Can you please clarify?

IDNA do not include mapping, so I presume you mean "IDNA would make this worse IF it mapped..."?
