@ymgan, that’s certainly something for GBIF to consider.
Note that it relies on scientificNameID being a text string that specifies the source of the identifier, in this case WoRMS. There are other available identifiers for “Siphonophorae”: see its Wikidata entry.
GBIF processing would also need one-to-many protocols (because there are so many ID-code sources) to check scientificName against scientificNameID and ensure there’s no disagreement.
I don’t think taxonID would be useful in disambiguation, because most of the datasets I’ve worked with use taxonID just to distinguish a taxon within that dataset alone, e.g. taxonID 1 > 1001 for a 1001-taxon dataset.
