Having a C binding doesn't mean you have to implement the bulk of the code in C.

For many embedded systems anything that has 'bindings' is bloatware.

Some platforms only have (bug-ridden, poorly supported) C compilers available: i.e. there's no other language to write in, let alone bind to.

Have you ever programmed a microcontroller?

(And yes, it would actually be nice to have reliable crypto on a micro-c.)
