I think that ASAs that are written in C will be written in that language for
reasons of extreme constraints. As such, they won't bother with a
library/API.  It will all be statically initialized globals and other stuff.
(Go read the Contiki code for an example of what I mean...)

Everyone else will write their ASAs in a higher level language: python, ruby,
perl, java, scala, *go*, maybe rust.   The really hard thing about the C api
is that doesn't deal well with indefinites like intents...
