They have its valid use to avoid situations like this:
| if cond1 && cond2 {
| if cond1 {
| do_stuff()
| }
| do_other_stuff()
| }
which can be rewritten like
| switch {
| case cond1:
| do_stuff()
| fallthrough
| case cond2:
| do_other_stuff()
| }
It's not quite visible due to cond* being short, but not so when they
involve comparisons against longish symbols exported from packages.
