--progress is not missing, but I see that it isn't documented. It was added in 72c5f88311 ("clone: pass --progress decision to recursive submodules", 2016-09-22). What you're suggesting makes sense, but as shown in that commit it's not easy for it to happen automatically, there's a lot of boilerplate involved.

But since you're interested you can see how to add new options with that patch, it should be easy for anyone not experienced with the codebase, it's all just boilerplate + adding a test.
