You can remove `SizedMap` on lines 94-101. Did you see any reason why a
`LinkedHashMap` was used? (I cannot, but this code has not changed in many
releases, so we should be sure its ok).

Nit: how about NO_DS instead of NO_DG?

Clarify what you mean by "Both should fail"? This test doesn't do a TLS
handshake. Maybe what you want to comment on is the order when checking is
enabled (i.e. cert with bad usage is always preferred last).
