It should be possible to declare a shared `@ref` only in the base table when using relational polymporphism about crystal HOT 2 OPEN

The documentation currently describes the from field like this:

from: - the name of the GraphQL type we're applying the reference to when using polymorphism

Based on #1876 and #1874, it seems like a better description might be:

from: - the name of the GraphQL type we're applying the reference to when using single-table (mode:single) polymorphism

from crystal.

I think what you're asking for is essentially inheritance. Interfaces in GraphQL do not perform inheritance - they just describe the interface that is expected, and it's up to the implementations to then provide fields matching the interface. Currently I'm following the GraphQL pattern. That said, for relational tables, there is effectively inheritance so I can see the value in that; feel free to work on a PR for it (for relational and single table interfaces only).

This is a feature that could be added long after v5.0.0 ships since there's already a solution, so it will be at the very bottom of my TODO list to fix myself.
