• libc field doesn't present in the lockfile pnpm/pnpm#9871 (comment)
• [BUG] libc field is missing in package-lock.json npm/cli#8514
• fix: arborist libc manifest npm/cli#7126

Currently, in order to build the correct dependencies tree, package managers either abandon checking the libc field, which causes both musl and glibc binaries to be downloaded in Linux environments.
Or they request complete metadata Accept: application/json during the fetch phase. Both approaches make installation slower and consume a lot of unnecessary traffic.
