+# Very early (unsure when) GnuTLS prefers RSA auth by default.  Later, but before 3.6.x, prefers
+# ECDSA but the client can be given a priority order to override that.  We're running the server
+# with no priority string given (tls_require_ciphers) hence default, and with both types of
+# server cert loaded (RSA first, though we don't document that as relevant and in testing it
+# does not appear to matter).
+#
+# GnuTLS 3.6.5 appears to ignore the client priority ordering, always choosing ECDSA if both
+# are permitted, if TLS1.3 is permitted, so we limit to TLS1.2.
