Current Windows documentation says for CSIDL_APPDATA / FOLDERID_RoamingAppData
at https://learn.microsoft.com/en-us/windows/win32/shell/csidl:

I was never able to find out what "typical" exactly mean. Is it something
configurable, or that can change at any point without any notice? I personally
don't think that trying to put some example value that may not be accurate for
the user is going to help, especially if that's not true on all currently
supported versions of Windows (and I don't know if that's the case, and even if
it's right now we will most certainly forget to update it the next time it
changes). Relying on dynamic variable resolution really seems like the best
thing to do.
