Currently the native authenticator requires a fully working mbedTLS port for the target board, which might not always be available. For platforms without a working mbedTLS port, it might be desireable to include a gutted mbedCrypto copy that only does RSA and SHA256, with blinding and PSS salt disabled so it can work without an RNG implementation. Security is not very important here so these tradeoffs are acceptable.
