While this may be true, it is usually a bad experience when the male part
gets severely bent or broken.......
It's not _that_ hard to replace. The trick, of course, is to cut the male
connector apart while it's still soldered to the PCB, and desolder it a
bit at a time.
If it's a straignt, vertically-mounted connector (not the right angle
type), it's often possible to desolder individal pins and push them out
of the moulding while hot. Then you can solder in a replacement pin,
taken from another connector.
