It's not really different to Arduino Shields and Raspberry Pi hats, no? Ignoring multi-purpose pins for GPIO or e.g. I2C, this is about matching the plugin module's pins to platform-specific on-board peripherals. Sticking the name to MikroBUS might be misleading, because this is AFAICT just a trademark for a specific connector pin layout. This concept could be applied for any kind of connector, where e.g. the I2C interface is mapped to i2c0 on one platform and to lpi2c5 on a different platform.
