It seems creating a stac item for s2 data processed with MAJA instead of Sen2cor is not possible.
stac sentinel2 create-item S2A_MSIL2A_20250805T101701_N0511_R065_T32TQT_20250805T125243.SAFE
produces
FileNotFoundError: [Errno 2] No such file or directory: '/test/S2A_MSIL2A_20250805T101701_N0511_R065_T32TQT_20250805T125243.SAFE/manifest.safe'
