I thought this is where constraints come in? If the specialization is
completely defined by the constraint class type, you can already generate
the specialization and reuse it?

At least that should avoid re-specialization of common container types for
basic class types.

But admitted, Delphi doesn't support inline with generics, in that FPC is
covering new ground.
