It originally had a footnote stating so, but that didn't show up in
the table/tabular environment, so I dropped it.

I think we'd rather have the reader chose and warn them.

Note that it said "14-18" and not "14,18":

14: 2048-bit MODP Group
15: 3072-bit MODP Group
16: 4096-bit MODP Group
17: 6144-bit MODP Group
18: 8192-bit MODP Group

So I suggest we either put in one group that fits the config A/B
(which group would that be? do we go into detail WRT DH parameter
sizes in the configs?), or all of them.
