Adapting to Bambu Connect means passing the print files to another app, and it's unclear if that app will work without a cloud account. Plus Orca does lose functionality like controlling the printer directly from the slicer, and one of the critiques of the new system is needing a separate app in the first place.

If you mean that OrcaSlicer will reimplement Bambu Connect protocols inside — I doubt that will happen, since Bambu Connect is not open source, so this would involve reverse engineering the protocols and potentially including Bambu Connect certificates.
