I am not a musl contributor and have no say in what it should contain or not, but why in hell a software implementation of a non-standard floating-point format that only its inventor seems to think has any concrete advantage over IEEE 754 belong in a libc the goals of which are below?

“lightweight, fast, simple, free, and strives to be correct in the sense of standards-conformance and safety.” (from https://musl.libc.org/ )

Posits are 1 out of 5 (I think they are free).
