Doesn't that also require whitelisting all free licenses used by a configuration?

Well, those have an actionable meaning (namely, who to contact regarding
problems in the package, and whether "nix-env -u" should consider a package
newer). OTOH, most users don't care whether a package is licensed under the
3-clause or 2-clause BSD license.
People who do care about the exact license of a package should use a tool like
Ninka do extract the actual license, rather than depend on meta.license (since,
as I said, it tends to be incomplete or wrong).
