Right, form follows function, so do it right and it will look right.
The factories didn't do anything more than use a hose clamp as that's good enough, that's all they ever do, there would be zero benefit to a fancy bracket so why waste money?
Anything more (in my opinion) looks a bit poncy and is starting to walk down the polished frame, anodised bolts, coloured brake pipes path.
