I don't think you even need to get into https://wiki.openstreetmap.org/wiki/Open_Data_License/Metadata_Layers_-_Guideline or the substantial question. https://wiki.osmfoundation.org/wiki/Licence/Community_Guidelines/Horizontal_Map_Layers_-_Guideline and https://wiki.osmfoundation.org/wiki/Licence/Community_Guidelines/Collective_Database_Guideline_Guideline make clear that you can use a particular OSM type (here, OSM-ids) as a collective database with other data types of non-OSM origin without triggering share-alike. It would be nonsensical for OSM-ids to come from a source other than OSM (hence, all OSM-ids are from OSM and are ODbL), so in this scenario it is easy to maintain conceptual separation of the ODbL and non-ODbL databases in the "collective". Since they're labeled "OSM-ids" even attribution is fairly easily covered. Surely there is a readme explaining what this metadata type is, just for use purposes.
