I think it's interesting because they seem to have built some vaguely pretty decent interfaces and drivers. Before that there were some attempts to make a rust embedded HAL but I think they were a bit too basic and didn't seem to get much traction. Also async interfaces are probably the most generic, because you can hook them up to superloops, single-threaded applications, and threaded code relatively easily (at least, more easily than the other way around), and IMO one of the big reasons Arduino stayed firmly hobbyist tier is because it was almost entirely stuck in a single-threaded blocking mindset and everything kind of fell apart as soon as you had to do two things at once.
