@cybereality : I understand they have a XAMPP stack running against which to perform database queries. So I reckon both versions would work from a Godot pov, that is performing http-requests against the patchy server, or with C++ and the database's API.
The first would then be your suggestion to script https requests in Godot without doing a module or extension, the second making a C++ module (Godot 3.x) or extension (Godot 4.y).
Hope that wasn't totally nonsensical :-)
