i'm not sure that's practical? all linux libcs i know of include these
headers. (though bionic only has them because glibc did. i'm assuming
the same is true for musl?)

i think there's obviously a question of "why aren't these uapi
headers, if stuff is using them?". just looking at Android, i see
sg3_utils, mtools, compiler-rt (for ioctls), and toybox (for the eject
command).

or perhaps --- even if most of the scsi headers should be non-uapi, is
there a subset of stuff that should be in uapi?

but "libc can use this header directly like it does uapi headers,
rather than having to need a human manually fix the header" seemed
like a step forward from the status quo where everyone's shipping
their own hacked-up versions of these headers?
