You don't know how right you are.
I bought a second hand frame (for the record: the seller was in Germany, not in Belgium). We agreed that he removes cranks (square taper!) and bottom bracket and sells it seperately. I paid the frame and shipping and waited. So far so good, but then that ... guy destroyed the threads in the left (square taper!) crank while trying to get it off. That was his problem, not mine. Then - without confering with me - he took an angle grinder, cut off the spindle with the crank and of course he hit the bottom bracket shell with the running angle grinder. 🤦♂️
Fortunately it was only roughly one millimeter and the left side and my plan was to use the frame with a cartrige bottom bracket for square taper cranks. Fortunately again I have a face milling tool for bottom bracket shells and know how to use it.

I posted that think no one in their right mind would go near a bike with a grinder. It must be a European thing.😏
