Well in its current state, it's rather limited in terms of direct usefulness, as the actual ISO images abound with all the permutations of languages, releases and OS variants and the app strings vary accordingly.
But since it's really just a batch file, you can easily adapt it to your particular source ISO and release.
I've used Nir Sofer's
UninstallView to get rid of all the bloatware that Microsoft adds to the OS these days and that will also allow you to change and update the batch file with the matching app strings to feed to DISM on your ISO.
It doesn't save much if it's just about deploying on a single system, but if you're trying to create a base line for several, it may be worth the effort.
And in any case it has the registry tweaks which allow you to install/update on systems which Microsoft has decided should die already, like my Skylake GT3e Iris 550 notebook with 16GB of RAM, that is still really far too useful to dump and generally one of the most compatible systems I have: It really runs every x86 OS I've ever thrown at it.... Except Windows 11 which actively cancelled it.
I'd still just wish some judge would force Microsoft to offer a default install without all that garbage and without having to disable phone-home data feeds for each and every (local!) user account.
I really hate it when servants/service providers believe they own the place where they are just meant to do the menial work of running applications.
