If I want to make a config file from the Proton VPN website and choose to use OpenVPN, I have the option to create a config file for Country, Standard server, or Secure Core. Conversely, if I choose WireGuard (which seems to be the strong recommendation in this post: https://protonvpn.com/blog/old-ovpn-configs), I can only pick from Standard server or Secure Core.

This may be fine for the occasional ad-hoc connection, but is not ideal when creating a config file for a router.

The Proton VPN website has the option to "Use the best server according to current load and position" when making a config file. That's what it is right now, but obviously will change over time. Relying on the same server may prove problematic if that's the only server configured and it goes down or becomes overloaded (assuming that Proton VPN and/or VPN client software will try another config if the first selected doesn't work).

Given (plus tier) country configs are already available for OpenVPN, it'd be great to see the same feature available for WireGuard.
