From my experience tables are much more used in publications than spirals.
Tables, flowing tables are basic for huge amount of any data intense publications, which means: a lot(!) of reports, any larger catalogue and big listings, any serious large publication probably will have at least few flowing tables. From that (data/tables) perspective: Publisher is nothing more than Designer - advanced software for building one page designs. This (huge) part of design market simply CAN'T use Affinity.
Spirals, on the other side, yes! I have used them: in 2003, for BRAVO magazine design...
