@nprofile1q... @nprofile1q... because of a bunch reasons it's not "just an object file" (because you can e.g. define a macro in one crate and use it in another so you have to pass over the macro information through), it's more language specific. But like, there's still a linker at the end of it all.

But like also, a whole bunch of stuff with "regular object files" assumes a bunch of C'ish stuff, which would place limits on other languages, and IMO it's not worth keeping onto it if it limits you.
