Quick question about changing front coils

[Abomb]

I’ve watched a couple of videos, as I’ve never done this before, and they always pop the upper ball joint loose, after tying up the calipers. I have drum brakes, why not just pop the bottom ball joint and drop the lower arm? That way I don’t have to remove the brake hose from the wheel cylinder, leading to rebleeding the brakes...I haven’t even removed a wheel yet to start this project, still waiting on my rear spring retainers in the mail...so let me know if there’s a reason not too...
