Hello!
We will think about it. At the moment the Configuration Generator proposes files for OpenVPN 2.4. A user must check "Advanced Mode" and then select "OpenVPN >= 2.5" to get files compatible both with OpenVPN 2.5 and OpenVPN 3, with the correct directives:
data-ciphers AES-256-GCM:AES-256-CBC:AES-192-GCM:AES-192-CBC:AES-128-GCM:AES-128-CBC
data-ciphers-fallback AES-256-CBC
But those files will not be compatible with OpenVPN versions older than 2.5. It's not easy when the user base is split between OpenVPN 2.3, 2.4, 2.5, 3.. with their mutual incompatibilities.
Excellent!
It's not planned at the moment, because tls-crypt made it essentially obsolete. We might instead consider OpenVPN over SSH in the future.
Kind regards
