Without having a good idea how feasible this is practically - it might be worth considering making `planet_osm_rels` a generic feature of osm2pgsql that is also available without slim mode.  I completely get that propagating relation tags to the member geometries is a more elegant solution within the design scope of osm2pgsql.  But this is a non-trivial problem when considered in a truly generic form (the concept of route relations is a very simple example where multiple relation membership have a fairly straightforward meaning - but that is not something that can be assumed to apply universally).

After all seen from the Postgresql side this is exactly what relational databases are meant for.
