The configuration file is suitable for organisations with an internal KMS server. Importation of the Office LTSC Professional Plus 2021 KMS key would be required.
This configuration excludes OneNote, Skype for Business & Onedrive for Business.
The Generic Volume License Key (GVLK) used is only for Office LTSC Professional Plus 2021.
Some configuration settings included don’t apply to Office LTSC 2021, such as SharedComputerLicensing and SCLCacheOverride.
The only issue I experienced with this configuration was the language ID. The installation failed when trying to use en-gb, this was the same issue as Office 2019.
