One question about this, can I also adapt it so that I have a table with all frames where I needed the backdrop template and add it here automatically with a for-loop?

Something like that?

AddOn.BackdropFrames = {
    "frame1",
    "frame2",
}
for i = 1, getn(AddOn.BackdropFrames) do
    local BackdropFrames = AddOn.BackdropFrames[i]
    if BackdropFrames then
        Mixin(BackdropFrames, BackdropTemplateMixin)
    end
end
