`Schema.extend` does not overwrite properties signatures if a duplicate property is given

Is there a reason why

Schema.extend

Schema.extend

doesn't overwrite properties signatures if a duplicate property is given?

const schema = pipe(
  S.struct({ a: S.string }),
  S.extend(S.struct({ a: S.number, b: S.number }))
)
// Duplicate property signature "a"

const schema = pipe(
  S.struct({ a: S.string }),
  S.extend(S.struct({ a: S.number, b: S.number }))
)
// Duplicate property signature "a"
