Does decoupling cost us model-specific capability?

Provider-specific features are real and are usually transient — a capability exclusive today is standard across providers within two release cycles. Building around one provider's extension buys a short advantage in exchange for a long dependency.

Because Centralpoint selects per request, a capability available from one provider can be used for the requests that need it while everything else routes on cost or locality. New providers and models arrive as adaptations every two weeks, so adopting a genuinely differentiating capability is a routing decision rather than a migration.
