How could the compiler decide if a NATIVE! can be inlined? You can

Probably, but it won't be REBOL; you couldn't treat code as data,
for example.

/Command is able to call external libraries not designed to accept
REBOL values, so I think there would be not so many problems in
calling a function DESIGNED to accept REBOL values and written in
a language that has primitives to handle those values.
