My exposure to the __Nuvoton MS51 microcontroller__ came about due to its use in a number of Pimoroni Breakout Garden products, initially their [IO Expander|https://shop.pimoroni.com/products/io-expander] board and then a pair of [RGB Encoder|https://shop.pimoroni.com/products/rgb-encoder-breakout] and [RGB Potentiometer|https://shop.pimoroni.com/products/rgb-potentiometer-breakout] that internally use the MS51. Recently they even added a tiny [Super Dinky Blinky|https://shop.pimoroni.com/products/super-dinky-blinky] LED blinker board that uses it, even providing github links and instructions on how to hack/reprogram the device. So it's clear Pimoroni have some engineers on staff who like the MS51 as a general-purpose controller.
