Wonderful. Here's one [https://forum.djangoproject.com/t/gsoc-2026
-interest-in-adding-support-for-generate-series-in-postgres/44362/2 forum
post] where Simon fleshes this idea out at more length.
Pravin started iterating on a design
[https://github.com/p-r-a-v-i-n/Generic---Relation---API-
Design/blob/main/RELATION_API_BLUEPRINT.md in a markdown document]. In it,
there was a first swing at representing a composite field with a `columns`
dict, and then some ideas about "intercepting" this later, but I agree
that Simon's proposal is more idiomatic, more general, and opens more
doors.
Pravin, would you be open to reimagining your design document as a small-
ish DEP that we could iterate on via a pull request workflow? From the
experience doing something similar with the `MAILERS` implementation in
Django 6.1, this won't arrest progress on the implementation, as you can
be iterating on a proof-of-concept in parallel.
