yes, it's too late in the cycle for this. We also don't have any
hardware to test it against - experience has made me reticent to ship
anything to do with PKCS#11 that we can test against only a single
software implementation.

A bigger problem however is libcrypto compatibility. The last time I
checked, libressl lacks the EVP_PKEY functionality for ED25519 keys.
They were considering it then, but I'll have to check back and see
what the status is.
