MDL is real today, but still in transition
The platform split is already visible in the product and repo structure, but MDL has not finished the full move from a first-party game runtime toward a fully generalized hosted platform.
Already in place
- A platform surface with builder-facing game workspace tools.
- Package-driven runtime branding and configuration.
- A tenant-routing direction that matches the long-term hosted model.
Still transitional
- The runtime still leans on a single selected package.
- Local package mode remains important in development.
- The eventual hosted data model is not yet the sole source of truth for all games.
How to think about MDL now
Treat MDL as the real platform entry point and deployment target, while recognizing that some game hosting behaviors are still moving from local-package conventions toward a fully hosted multi-tenant model.
Practical takeaway
Build toward the platform model now, even when a current workflow still uses transitional wiring underneath.
