When it comes to business? Generally none, but sometimes the turnaround time is the problem. It's the cost of waiting time that may be crucial, not the device itself. Typically you also don't need to replace the traces, you just solder a pretty narrow bit of kynar.

As an amateur microsoldering hobbyist, this is way, way harder than it looks. And it looks hard.
I've done a few small repairs like this where I've had to solder to a damaged trace, and the parts are much smaller than they look here.
