I used to work for an IoT connectivity provider (think SIM cards, eUICC etc); I know that some of the manufacturers of various devices have been investigating adding cellular and soldered eUICC (ostensibly for diagnostics, warranty etc).
So it's not even that it won't be long; I'm sure they already have designs and are just waiting for eUICC support to catch up.
