Comment (by cdestigter):

 Apologies, I had mis-remembered why we did this.

 It's actually because

 (a) we wanted to be able to use CRSes that Postgis doesn't know about.
 Just using an integer SRID requires that that CRS be in `spatial_ref_sys`

 (b) We wanted to ensure we have a single source of truth for CRS
 information (proj.db) - and not have to sync patches into PostGIS if we
 change proj.db by adding custom CRSes etc.
