Probably would not make you giggle when you hit a bump and it snaps the spring perch off of the axle. That has happened, with disastrous consequences. Think about it; when the spring compresses, it spreads. If there is some angle on the shackles, it easily spreads the shackles down and out. If the shackles are flat, it imposes side loads on the spring perch as the spring tries to spread under load.
There are warnings about too-flat shackles on older threads.
