[Read-only notification of GnuTLS library development activities]

> `gnutls_hmac_fast(GNUTLS_MAC_SHA1, NULL, 16, text, sizeof(text), digest);`

This is an API mis-use, which is out of scope of our threat model: https://gitlab.com/gnutls/gnutls/-/blob/master/SECURITY.md?ref_type=heads#threat-model

If we were to address it, that would be adding an `assert` to be clear that it is a programming error of the application.

Please stop reporting issues in this class of problems.
