As John already pointed out, microkernels are working all around you,
e.g. in cell phones, cars, DVD players, data acquisition and other

Many programming systems (Forth, Java...) allow to produce turnkey
applications, running on a naked hardware, since decades.

Other classifications separate general purpose (C...) from specialized
(SQL...) languages, or compiled (C...) from interpreted (SQL...) or
emulated (Java...) languages.

Your "microkernel" languages IMO fall in the category "highly platform
independent" languages, which only require the installation of the
according interpreter or emulator (VM) on a target system.
