I get the sense Miitomo's more of Iwata's baby and it's something that Kimishima and maybe some of the newer leadership staff at Nintendo isn't as invested in (see also: Nintendo's QoL Sleep Sensor which also seems to have been put on the back burner).
Just a prediction but I think under Kimishima Nintendo will push more for the big gun Nintendo franchise characters to go mobile not something like Miitomo.
