Train wreck on 06 March 2018
From a cost standpoint, SE makes the most money...
Digital > Disc > Cartridge, so making the least amount of cartridges means the most bang for their buck. The game itself had a very limited budget and I am sure SE was not willing to break the bank on media production.
From a telemetry data standpoint they are seeing that demand for Switch physical for this game is low, so they are treating it on a case by case basis.
Any more than that would be looking at it from a fanboy prescriptive (Prior gaming arrangements, SE shipment/publishing aggrements, the Nin/Sq relationship in the SNES days, etc)
