How so? The commit specifically constrains the quirk only to
affected dual GPU MacBook Pros. So I don't quite see how this
would affect other T2 models?
And what kind of issues are you seeing? Could you provide
specifics please?

We generally try to avoid command line options. The kernel
should automatically determine whether to apply the quirk
or not. So I think the proper solution is to amend the
quirk such that it's applied to additional models or not
applied under certain circumstances.
Thanks,
